64qam调制解调的Matlab程序仿真代码，对研究64QAM很有帮助-64qam modulation and demodulation process of the Matlab simulation code, very helpful for research 64QAM

这是一个实现linux系统下的scp的命令相同功能的程序，客户端和服务端通信使用了自己定义了的通信协议。 文件传送协议格式： 服务器路径#服务器上的文件名#操作类型#文件大小 操作类型：0代表上传操作 1代表下载操作 文件大小：上传下载的文件大小 服务器返回的消息类型： 0 ：服务器创建文件失败 1：服务器操作成功 2：文件大小不同 （未实现） 注意： 1:正则表达式没有实现 2:其余实现 3:服务器可以为多个客户端服务，用多进程实现-This is a linux system realize the scp command functions the same procedures, client and client communication services using its own definition of the communication protocol. File Transfer Protocol format: server path# Server 23 file name! Operation type# File size operation types: 0 From operated on behalf of one operation on behalf of download file size: From the size of the downloaded file to return to the news server type: 0 : The server failed to create file 1: Server operation successful 2: documents of different sizes (not realize) Note: 1: regular expression did not realize 2: the rest of the realization of 3: The server can service multiple clients, and realize multi-process

我们自己创建各个的头部,系统只是把它们发送出去. 在实例中,由于我们要修改我们的源IP地址, 所以我们使用了setsockopt函数,如果我们只是修改TCP数据,那么IP数据一样也可以由系统来创建的. -To create all our own head, the system only to send them out. In the example, because we have to modify our source IP address, so we use the setsockopt function, if we just amend the TCP data, then the IP can also be from the same data system to create the.

自己用VB写的串口调试程序，对于单片机之类的调试非常好用，自己感觉比网上能下到的那些好用-Its own serial port using VB to write a debugger for debugging single-chip microcomputer, such as very easy to use, their own feelings than the bottom line of those who can use
