    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.

    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.

  • DLL注入

    DLL注入,就把什么枚舉進程、查找窗口和進程特權設置那西東西省了。 附件中帶了一個testDll.dll,是我寫的一個測試DLL,因為一般的DLL注入進去了可能沒反應,所以在我寫了個DLL,在里面加了MessageBox,可以彈出來,這樣就知道DLL運行沒有。DLL是VC++寫的,因為我用的是VB迷你版,只能寫ActiveX DLL,而這種DLL不能用來注入(我寫了個,在Main函數里寫了個MsgBox,啟動對象設為 Sub Main,發現可以注入,但沒有MsgBox出現),如果誰要DLL源碼就回貼說,我發上來。

    PC機與智能儀器串口通信 MSComm 控件 MSComm 控件通過串行端口傳輸和接收數據,為應用程序提供串行通訊功能。 語法 MSComm 說明 MSComm 控件提供下列兩種處理通訊的方式: 事件驅動通訊是處理串行端口交互作用的一種非常有效的方法。在許多情況下,在事件發生時需要得到通知,例如,在 Carrier Detect (CD) 或 Request To Send (RTS) 線上一個字符到達或一個變化發生時。在這些情況下,可以利用 MSComm 控件的 OnComm 事件捕獲并處理這些通訊事件。OnComm 事件還可以檢查和處理通訊錯誤。所有通訊事件和通訊錯誤的列表,參閱 CommEvent 屬性。
