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)

matlab中PCA-fisher判别法，对数据降维有很好的效果，附件中是matlab2007源程序，不同的matlab版本需要稍微修改一下；谢谢(Discriminant law PCA-fisher MATLAB, to reduce the dimension of data have a good effect, accessory is the MATLAB2007 source code, a different version of the MATLAB needs to be slightly modified thank you )
