说明：  ecg信号读入后后期处理，滤波，并进行阈值处理。(After reading ecg signal post-processing, filtering, and threshold processing.)

一个有关支持向量机的matlab工具箱，内含支持向量机理论的简单介绍和matlab工具包(One on support vector machine matlab toolbox, including support vector machines and a brief description of the theory matlab toolkit)

根据GSM协议，实现8PSK调制。其中OPSK是主函数(According to the GSM protocol, to achieve 8PSK modulation. Which is the main function OPSK)

利用经典MUSIC算法及MMUSIC算法估计波达方向，绝对可运行！程序没错误！(Using the classical MUSIC algorithm and MMUSIC algorithm to estimate DOA, absolutely can run! Program did not wrong!)

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)
