用TCP获得网路标准时间来设定您的PC时钟(Set your PC clock with TCP to get network standard time)

这个例子显示了如何使用的Windows RegisterDeviceNotification功能，收到WM_DEVICECHANGE消息(This example shows how to use the Windows RegisterDeviceNotification function to receive WM_DEVICECHANGE messages)

基于VC++的一个串口通讯类应用实例,有兴趣的朋友学习一下。(VC++ based on a serial communications application example, friends who are interested to learn about.)

实现物理层网络编码的仿真，此为无信道编码环境下实现的(network coding)

使用 VC++ 调用微软蓝牙 API 函数的示例代码。可以使用 VC++6.0 至 VC++2010 编译代码。(Using VC++ call Microsoft Bluetooth API sample code. You can use VC++6.0 to VC++2010 compiled code.)

语音编码方案的选取对移动通信系统的通话质量、信道容量等有重要影响。本文讨论了TD-SCDMA系统中AMR语音编码的自适应机制，同时分析了AMR中代数码本线性预测(ACELP)算法及实现过程。该方案可以在一块TMS320C5510上实现。(The selection of voice coding schemes for mobile communication systems the quality of the call, such as channel capacity have had a significant impact. In this paper, TD-SCDMA System AMR Adaptive speech coding mechanism, at the same time analysis of AMR in the generation of Digital Linear Prediction (ACELP) algorithm and the realization of the process. The program can be achieved in a TMS320C5510.)

void swap1(int x, int y) //值传递 void swap2(int *px, int *py) //指针传递 void swap3(int &x, int &y) //引用传递 的使用(void swap1(int x, int y) //值传递 void swap2(int*px, int*py) //指针传递 void swap3(int &x, int &y) //引用传递 的使用)
