simulation of Communication Systems

说明：  在MIMO系统里 2发2收天线，采用Alamouti发案编码的无线传输系统在瑞瑞丽平衰落信道下的误码率性能仿真，系统采用调制方式为QPSK。(MIMO 2 send and 2 receive antenna ,)

频分复用信号的生成以及演示，与英文工具书匹配，很好用！(FDM signal generation)

c#编写串口通讯代码 多线程实现,老外写的，很有用，很全面(c# write serial communication code multithreading, written by foreigners, very useful, very comprehensive)

随机方法构造的LDPC码，码长可变，无四环(random ldpc,code length can be changed)

AM调制与解调，信息信号和载波信号经过AM调制并加噪得到AM信号的频谱，再经过带通滤波器，相干解调，低通滤波后得到解调后的信号。(AM modulation and demodulation, information signal and carrier signal through AM modulation and noise to get the spectrum of AM signal, then through band-pass filter, coherent demodulation, low-pass filter to get the demodulated signal.)

相位和载波估计的算法，用于通信中的同步估计。(And carrier phase estimation algorithm is used for communication synchronization estimation.)

this is a paper for pcf beam splitter!

MFC编程 实现数据绘制成曲线。经兄弟推荐最终决定用两个控件MCSCOMM与TeeChart来完成此任务。MCSCOMM控件时vc自带的串口控件(MFC programming realizes data plotting into curves. After recommendation by brothers, we finally decided to use two controls, MCSCOMM and TeeChart, to accomplish this task.)

说明：  基于经典music算法及其修正算法的DOA估计以及性能仿真(DOA estimation and performance simulation based on classical Music algorithm and its modified algorithm)
