详细介绍了matlab中的常用命令集，按照从a到z的顺序排列。(Described in detail in the commonly used matlab command set, in accordance with the from a to z of the order.)

这是《Space-Time Codes and MIMO Systems》书中第四章的源程序，包括stbc2x1,2x2,3x1,3x2还有当信道具有相关性时的stbc2x2,4x4等多发多收等的源程序。(This is the "Space-Time Codes and MIMO Systems" source book, Chapter IV, including stbc2x1, 2x2, 3x1, 3x2 as well as when the channel has a relevance stbc2x2, 4x4, etc., etc. overcharged multiple source.)

用DB4小波进行多尺度分解，分解级数为6层的降噪程序(DB4 Wavelets )

程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制； 根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声； 接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。 结果表明10^-3对应大约12->13dB(Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB)
