傅立叶变换是一种线性的积分变换，作用是把信号在时域（或空域）和频域之间变换(Fourier transform is a linear integral transform, which is used to transform signals between time domain (or space domain) and frequency domain.)

用c语言写的ldpc码的最小和算法译码程序。(The codes are about ldpc decoding,using min-sum algorithm by c++.)

C++编程实现的PLC梯形图编程环境，很不错(C++ programming of PLC ladder programming environment, very good)

说明：  在C#环境下利用逆波兰式开发的代码较为精简的简易计算器。(Simple calculator with simpler code developed in reverse Polish style in C# environment.)

基于TCP的网络编程，用C#语言编写，实现客户端与服务器之间的通信(TCP-based network programming with C# language, the communication between the client and the server)

面向连接的服务器流程中，必须设置服务器套接字为监听状态；而客户机则是主动连接。无连接客户机和服务器。无连接客户机和服务器在调用的函数方面没有区别，区别在于服务器一般先启动recvfrom等待客户机的数据。客户机和服务器的通信过程为客户向服务器发送数据，服务器收到数据后给予应答，通信结束。-connection-oriented server process, you must set up to monitor server socket state; While the client is active connector. Without connecting client and server. Without connecting client and server in a function called no distinction, the general difference is the server for first launching recvfrom client data. Client and server communication process for clients to send data to the server, the server data received responses and communication end.
