实现时域与频域均衡MMSE方法的比较 采用64QAM调制(Comparison of the time domain and frequency domain equalization MMSE method)

卡尔曼滤波器是一个（最优化自回归数据处理算法）。对于解决很大部分的问题，他是最优，效率最高甚至是最有用的。(The Calman filter is an (optimized autoregressive data processing algorithm). For solving most problems, he is the best, the most efficient and even the most useful.)

说明：  matlab的bpsk，qpsk，msk，qam打包下载，不是自带的程序函数。按照通信框图做的程序(MATLAB，bpsk，qpsk，msk，qam)

该程序给出了LDPC编译码程序的经典算法，即BP算法，性能比较好(The program gives the classic algorithm LDPC decoding procedures, namely BP algorithm, the performance is better)

串口程序，实现串口发送，接受文件，用户只有少做修改就可以为自己所有(Serial procedures, implementation serial send, receive documents, the user only a few modifications can make all their own)

在光纤通讯仿真中，产生QPSK，16QAM，64QAM信号，并添加激光相位噪声和自发辐射噪声(In optical fiber communication simulation, QPSK, 16QAM, 64QAM signals are generated, and laser phase noise and spontaneous radiation noise are added.)

利用C++实现的一个即时通讯系统的客户端。传输层采用的是TCP协议。这是本科时候的毕业设计，最后评定为优，希望对一些朋友能有所帮助。(The use of C++ implementation of an instant messaging system client. Transport layer protocol used is TCP. This is the time of undergraduate graduation project, and finally classified as gifted, in the hope that some of my friends can be helpful.)

wcdma上行扰码生成，严格按照3gpp 25212进行编写，有多种实现方式(wcdma uplink scrambling code generation, in strict accordance with 3gpp 25212 to write, there are a variety of ways)

8psk 数字解调器的simulink仿真(8psk digital modem s simulink)

西门子PLC第三方通信驱动，包括PPI,MPI,ISO-TCP等所有通信协议(Siemens PLC, third-party communications drivers, including PPI, MPI, ISO-TCP communication protocol)
