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.

description of each sub-section. The design consists of:
· PowerPC processor
· PLB-OPB bridge
· BlockRAM Memory Controller
· SDRAM Controller
· Two GPIO ports
· A UART Port
· External SDRAM
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(qiáng)制聊天器
大家好..我是愚罪..QQ：303931726
今天教大家來用VB做QQ強(qiáng)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(yàn)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.
