Alamoutiwork
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)
