说明：  这是一个基于OPtisystem下的对于16QAM信号的仿真，可用于通信工程作业的一般仿真系统。(This is a simulation system of 16QAM signal based on OPtisystem, which can be used in general simulation system of communication engineering operation)

The following file contains three types of digital communications sampling. Contains ideal sampling, natural sampling and ZOH sampling, operate only for one single frequency signal, can be modified to add multiple signals with a base frequency. Greetings, I hope it helps.

说明：  一些时反的例程和其他代码，mat文件是信道信息(The Mat file is the channel information. There are some examples of the Time Reverse and communication system.)

采用Log-BP算法的LDPC码译码仿真程序,给出了不同信噪比下误码率和误包率的统计图,用matlab和Cc-mex程()

手机中RF的基础知识，想学习RF知识的朋友有一定的帮助作用。 (phone RF the basic knowledge, to study RF knowledge friends to a certain extent help.)
