LTE application: Signal PSS and EU synchronization problem


Just as I suspected, samples received on the receiver side are only cross correlated with the PSS sequence (PCI mod 3) = 0, this is the reason why the synchronization does not work when the eNB transmits with a (PCI mod 3) 0. The PSS sequence (PCI mod 3) = 0 is integrated as a time fixed signal of the domain in the FIR filters although (the two who treats I and rated a Q of the received signal handling complex). To change this and to implement a different sequence of PSS, should open the basic FIR blocks Xilinx generator and change the sequence.

I got some guys from support LabVIEW Communication an updated version of the "LTE Cross Correlation.gcdl" function that implements a selective control for the value (PCI mod 3) and seems to change the PSS sequence within blocks of FIR. I post here if someone has the same problem. Although I have not tried myself yet.

  • Pinch and Zoom - synchronization problem

    Hello

    Since v25, iPad Apps have a pinch and Zoom synchronization problem. If hitting swipe to a page, you cannot directly Pinch & zoom, using the two finger gestures. Firstly, it must wait 1 to 2 seconds (whats darn long) until you can zoom. Even if the PDF page is fully loaded (already sharp/readable).

    On some pages that do not have something different than the other pages, you must first zoom out, before zooming in works.

    Very strange problem. Someone at alse noticed the same thing?

    I'm using the latest tools of InDesign CS5.5 v25.

    Kind regards

    Yves

    We have seen problems with pinch and zoom on v25. It is not so much a timing problem that the gesture is very sensitive to how far your fingers are when you start pinching. We turn to her with a fix in v26.

  • Audio film blackBerry Smartphones BlackBerry Torch and lag synchronization problems

    Anyone has this problem where after some time watching a movie the audio appears trolling out and synchronization of his lips is the way out. The image also appears to stutter and lag? Any who have the same problem and or know to remedy this? The files work fine on my mac, but when on the Blackberry, they have this problem. Its quite annoying, so anyone with a fix or a solution that had the same issues please let me know how I can sort. Thank you very much

    Hi RADIKAL69

    If you watch a movie, I would recommend ensuring that no other application works (apart from the basic such as Messages, home, telephone, BBM and browser apps).  You can do this by pressing the menu button to see what applications are running and enter each of them to close in now the back button, or by pressing Menu > close/exit.  In addition, for best performance, disable all network connections.

    If the BlackBerry is your film treatment and trying to deal with other tasks in the background, this could cause some lag in the audio synchronization.

    Thank you

  • (FirePower 7010 and FireSight) synchronization problems

    Hello! I have some problems with the power of FIRE and fire show.
    I have error and I need help.
    I have error on the status of synchronization of time FIRESIGHT:Module: 192.168.10.10 is out-of-sync.
    I can say that time is the SAME show of fire and firepower. How can I solve a problem? Where can I see the logs? Thank you!!!

    Your police tells the module to use for NTP - your FireSIGHT or another NTP server?

    If FireSIGHT is on a virtual machine, it is recommended to use it as a NTP server for your managed devices.

  • Application modular Flex and BlazeDS serialization problem

    Hey there,
    I write modular Flex application using BlazeDS to communicate with managed by backend Java spring. I created Java objects on the server side and the relevant ActionScript objects in flex.

    I used RemoteClass metatag to serialize objects from flex to java. Everything works perfectly fine, when I work with the objects that first loaded module. I am able to serialize the form of objects as Java. But when I reload module or load another flex module I'm losing the types of objects serialized. I get this error message then:

    faultCode:Server.ResourceUnavailable faultString: 'Can't call method "updateProfile".' faultDetail: ' types of expected arguments are (com.konrady.cms.entity.User), but provided types have been (flex.messaging.io.amf.ASObject) and processed (null).

    I tried to invesigate this question, and I'm sure this is the problem with loading flex modules. When I insert ModuleA first of all, I am able to serialize the quant to Java objects. But when I load moduleB, I can't serialize objects and more. Loading moduleA again after that ModuleB are also not possible to serialize objects.
    When I load moduleB firstly I can serialize objects of it. Reloading flex modules brokes Serialization...

    Someone has encountered this problem before? I will be grateful for any piece of advice.

    Ouch, I hope that someone with a full understanding of these multi-application configurations will come to your front rescure I spoil completely.

    I would like to tell you of a long series of publications dealing with the complexity of such a request in the middle of the AIR [which is my case], but due to the mishandling of the code formatted in this forum tool, which deals as the thread to 'How to Test AIR 1.5' in the developer forum is almost impossible to follow and , at the end of the day, he never gave a "How-to" document as I had hoped.  Under "can someone Open the Black Box" in the Adobe AIR forum, there are some ideas that might be relevant.  To reduce the time of download of network for the scheme - not really reduce congestion of memory - I configured my use of SWFLoader in the AIR application to successfully benefit from the Flex Framework RSL.  I don't think that the possibility of using BlazeDS classes in the scheme is directly related to this difference, but it can be indirectly related.

    Following this line of thought, you could get the 'how to debug Actionscript to Java serialization problem' that I posted on the forum Configuration and commissioning, which can help, but it seems that you have found the information of stack trace good to help in your search for failures.

    The new information - or at least what I had not detected from your previous post - seems to be this:

    Home - or not properly accesses remote objects, I'm not clear.

    Load A sub-application successfully access Remote Objects.

    Load sub-application B fails when you try to access remote objects.

    This seems to make clear that "dumping" is not what is causing the failure.  I think, then, is that your problem has to do with loading, and now I have to expose my ignorance to the world and how it was that I finally managed to get my multi-application to subsequently work issues at stake.  If it helps your big case, or if only it gives off just using one or several of the teams in question Adobe - Flex SDK team, team air, BlazeDS team - then we all benefit.

    Somewhere that I can't find now, there is this big PDF file describing the scenarios to pump Flex of MashUps and other environments where a disconnnected development team may have to deal with different versions of RSL - done one or two side-notes on the AIR, it focuses on the Flex.  From there on, I won some glimmer of an idea of the ApplicationDomain class and class related SecurityDomain.  I could not, on a bet, give you a clear statement on the results of the use of the different options.  The code I use to achieve successfully the dynamic loading of my scheme via the SWFLoader is loaded with comments showing that I n "t got a clue.  I tried all combinations; This is what works for me:

    var context: LoaderContext = new LoaderContext();

    context.allowLoadBytesCodeExcecution = true;

    context.applicationDomain = ApplicationDomain.currentDomain;

    var swfLoader:SWFLoader = new SWFLoader();

    swfLoader.trustContent = true;

    swfLoader.loaderContext = context;

    swfLoader.source = byteArray;

    The byteArray was populated by readBytes() starting from a FileStream.  As I said, my use case is sub-appliciations Flex and/or air base running in an envelope of AIR.  Presumably, you get to the same place in pure Flex using SWFLoader.load () after you have configured the ApplicationDomain or SecurityDomain via the LoaderContext.

    All I can hope. After dragging you in all this rubbish is the link of the duration of the BlazeDS code begins to work for you, as it did for me.  In particular, which does not [even though I was debugging problems other than BlazeDS in time] was to set the LoaderContext this way:

    context.applicationDomain = new ApplicationDomain (ApplicationDomain.currentDomain);

    or was this another incantation:

    context.applicationDomain = new ApplicationDomain (null);

    These three variants have the world to do with the way the runtime detects and calls methods on classes in the application.  Only the first allows me to work successfully with RemoteObjects in any subsidiary application that happens to need support on the server side.

  • Smart playlists and music synchronization problem Apple

    Why I always found rather strange Apple music library system, for example, I can't understand you need 'heart' a song or just add music manually to Apple to have added to your smart playlists, I use since a long time some smart playlists that get the last song that I added to lybrary filtered by rating, showing those with at least three starts a heart of GOLD.
    Well well, if I like a song or add it to my library to a music playlists from Apple on my iTunes Mac or PC, for example "Hot 50" Filtr, I can actually find on my vision of music, but not in my smart playlists. Do the same thing to the iPhone gets the song immediately added to smart playlists.
    Maybe it's a bug, forcing same synchronization or wait a few days doesn't fix it, until I use my iPhone to do the same.

    I know that just 'like' or 'TRIPHASEE' as you called him alone won't add music to your library on your Mac and so it will not be added to your smart playlists. You must ADD the song to your library for that to happen. "Loving" is a song - what Apple music - effects allegedly only the choices Apple suggests in the section for you.

    Not sure why as you claim this happens on your iPhone, because I don't think that the system is supposed to work that way - but I have been wrong before.

  • BlackBerry smartphones duplicate appointments and calendar synchronization problems

    I use Outlook 2003 and the Blackberry Curve with v4.2.2.180 software.  I don't use Enterprise Server.

    When I sync my BB with Outlook, he began to do some weird things.  First of all, he wants to delete my Outlook items.  Second, he changed the title of a recurring appointment for no apparent reason.  I have to fix things, tried to set the configuration so it records only deletes or moves on the BB and set the configuration in advance so that conflicts are always resolved in favor of Outlook, but when I synch, he wants to still remove 22 items in my Outlook calendar and add one bunch of others.

    How can I get to sync properly?

    Do I have to clear the calendar on the BB and then start Outlook?  How do I do that?

    Thank you

  • Muliple USRP RIO 2943R, synchronization and phase-locking problem

    I use 8 USRP RIO 2943Rs transmission of signal and receving (4 for Tx) and 4 for Rx I'm using the "signal-based" method for synchronization of all devices. And I did it. I tested the system the result is very interesting:
    1. when I put the sampling rate of less than 40MS/s IQ, I can obversve very good phase locked Tx and Rx signals (I use a sine wave CW for tests), please refer to video joint (locked 40MSs)
    2. BUT, when I put the IQ more than 60 MS/s sampling rate, I'll lose phase lock. Please refer to unlocked 60MSs. My goal is to run the system at 120MS/s
    I have doubt as to if the problem comes from two sides:
    a. the sync methed isn't fair
    b. OR, should I increase the clock that operates the loop 'In Streaming radio engine' in the FPGA VI. as shown in the following image.

    I would like to ask experts in the forum to discuss the solution of this problem.

  • iPod connection and synchronization problems classic160GB

    I have a well taken in charge iPod classic 160GB. Worked perfectly until...

    Since the upgrade to the latest OS (iMac), I've been prone to random error when updating of my music. Essentially (1) the device is still connected and there is no apparent way to perform a good ejection process (2) and synchronization fails after many hours and don't care only about 100 songs.

    Thus, it seems that the iPod is ok mechanically. I have reset the device and formatted the HARD drive. This allowed then the synchronization process works correctly. Yesterday I downloaded the songs on the iTunes store and wanted on the iPod - same problems error has occurred.

    Would it not make sense to go back to an earlier version of the operating system? and iTunes? (same iTunes appears unstable now...)

    I see that this timing issue is quite common with this unit holders and it seems to be common, because support was arrested for this camera - I'd be cynical? Why isn't Apple in the face of what it comes to very bad reputation management - total contempt for Affairs of its user base?

    I always use what is apparently a good piece of hardware, but I'm extremely frustrated as a user. Any body found the corrective action? If so, what is it?

    LAST: I left Apple and bought a Sony HD camera. Why? as a result of these frustrations. I'm now evaluate whether to consider other Apple devices that are close to replacement (viz, Ipad, MacBook Pro (17 "), iMAc) with non-Apple devices. This is how frustrated and I'm in a bad mood.

    Please, if you know a solution, I am very willing to try that.

    Problems with synchronization is often caused by a hard drive which becomes unreliable.  Hard drives are mechanical and ends by fail, computers and iPods.  I have much older iPods (4th gen, 3rd generation and iPod mini) that are more than 10 years at this point.  They still work perfectly fine with the latest version of OS X and iTunes.  I replaced the fragile hard drives in three of these iPods with Compact Flash card or an SD card on an adapter.  For the 5th generation and later iPods, you can look here for more information

    https://www.iFlash.xyz/

    I see that this synchronization problem is quite common with this unit-holders...

    It's not just 'common good' considering there are millions of iPods (with storage on hard disk) still serving there.  However, if you see more cases of these days, the reason is obvious.  They age, on average.  The iPod classic model was released back in 2007.  Old things tend to start fault for various reasons, including defective hard drive.

    I have the HTC Droid Incredible 4 G LTE and whenever I try to connect it to the Manager of HTC, it does not work. My phone says: "Unable to open HTC Sync Manager on your computer. Check that the application is installed and open. " The Manager is open on my laptop and I just re downloaded yesterday. The Manager is currently up-to-date, but my phone does not always connect.

    According to HTC, the HTC Droid Incredible 4 G LTE is not compatible with HTC Sync Manager even if HTC Droid Incredible 4 G is.  There are forums from HTC that would give advice.

    You will have to remove it then use HTC Sync instead.  Download & its installation instructions are on this page HTC.

    My HTC Desire X can use HTC Sync Manager, but I have tried both and neither of them is very useful software.  Two of them, for example, to synchronize favorites of IE in a simple list in a single folder [that is, they lose the folder structure that you can use in favorites of IE in order to manage the potentially large number of items you have in there].

    Good third-party synchronization - MyPhoneExplorer, BookmarkSB & MeercelRSSDemon software

    If you install HTC Sync, you will find useful drivers because they allow you to use a third-party synchronization software like MyPhoneExplorer.  MPE allows synchronization directly via a USB connection if you do not use to the top of your phone data allocation synchronization with your own data [you can also synchronize using WiFi Hotspot from your phone or a WiFi network].  I used the MEP with both Android 4.0 and 4.1.  You can also see their section English Forum for the guide very useful to establish things.  If you install GPP, while the phone is connected, then the necessary MPE 'client' should automatically install on the phone as well - otherwise go to MyPhoneExplorer Client - applications Android on Google game to get the customer.

    Synchronization of MS Office - Outlook 2007

    MPE can synchronize Outlook calendar, Contacts, Notes and tasks.

    Sync IE Favorites

    If you try to synchronize include Favorites of IE [Favorites] so that you can use the MPE to synchronize your exported favorites of IE list [I can explain if you want] on the phone and then use BookmarkSB to import your IE favorites through the Android default browser [, then, if necessary, Chrome can import them into him there].

    Synchronization of IE RSS Feeds

    I export my IE FLOW RSS to opml file, and then synchronize this file to the phone & import it into Demon RSS de Meercel.  It's heavy, but I do not add flow additional RSS very often is not too heavy.

    Other synchronization files

    I use the MPE for all my synchronization, including Music & Office-type files [I don't know if your phone comes with MS Office-equivalent application].  You'll want to look at the files, settings, MPE, MultiSync.  If you have a specific example of synchronization you want then post it here & I'll try to explain the parameters useful for her.
