[Modem program] Alamoutiwork DL : 0: 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

[MultiLanguage] 01576960Beaulieu DL : 0: 通过MATLAB软件；通过仿真得出性能曲线；从而比较bpsk的性能-The bit-error rate (BER) of binary phase-shift keying in Rayleigh fading, using the Alamouti transmission scheme and receiver selection diversity in the presence of channel-estimation error, is studied. Closed-form expressions for the BER of log-likelihood ratio selection, signal-to-noise ratio (SNR) selection, switchand- stay combining selection, and maximum ratio combining are derived in terms of the SNR and the cross-correlation coefficient of the channel gain and its corrupted estimate. Two new selection schemes, space–time sum-of-squares combining selection diversity and space–time sum-of-magnitudes selection diversity, are proposed and proven to provide almost the same performance as SNR selection, but with much simpler implementations. The effects of channel-
