This paper examines the asymptotic (large sample) performance of a family of non-data aided feedforward (NDA FF) nonlinear least-squares (NLS) type carrier frequency estimators for burst-mode phase shift keying (PSK) modulations transmitted through AWGN and flat Ricean-fading channels. The asymptotic performance of these estimators is established in closed-form expression and compared with the modified Cram`er-Rao bound (MCRB). A best linear unbiased estimator (BLUE), which exhibits the lowest asymptotic variance within the family of NDA FF NLS-type estimators, is also proposed.

The last step in training phase is refinement of the clusters found above. Although DynamicClustering counters all the basic k-means disadvantages, setting the intra-cluster similarity r may require experimentation. Also, a cluster may have a lot in common with another, i.e., sequences assigned to it are as close to it as they are to another cluster. There may also be denser sub-clusters within the larger ones.

用VB做QQ強制聊天器 用VB做QQ強制聊天器 大家好..我是愚罪..QQ：303931726 今天教大家來用VB做QQ強制聊天器..... 廢話不多說了``` 直接打開VB 新建一個EXE文件..新建一個Text和一個Command按紐 最后直接把代碼寫上去就可以了... Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _ (ByVal hwnd As Long, _ ByVal lpOperation As String, _ ByVal lpFile As String, _ ByVal lpParameters As String, _ ByVal lpDirectory As String, _ ByVal nShowCmd As Long) As Long Private Sub Command1_Click() ShellExecute 0, "open", "tencent://message/?uin=" + Text1.Text, "", "", 1 End Sub 可以了...生成試驗下..我就不美化了..你們可以去美化下``` 看。。成功了

This a very simple baseband simulator for SC-FDMA system. This simulator is part of the upcoming book “Single Carrier FDMA: A New Air Interface for Long Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J. Goodman at Polytechnic University. The purpose of this simulator is to give some concrete idea of how SC-FDMA system works. It does lack many realistic and sophisticated features such as channel coding, time-varying fading channel model, soft decision decoding, etc. Regardless, I am hoping that it will help you understand SC-FDMA which is a fairly new development in 3GPP LTE.
