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)

CalculatioofPartitionConvolutionBasedOnTheMATLAB
线性卷积要求两个输人序列具有持续时间，但在实际应用中，可能遇到输人序列具有无限持续时间的情况。在这种情况下，分段卷积是一种有效的解决方案。文章讨论了计算分段卷积的两种方法。仿真试验表明，分段卷积方法正确且高效。(The linear convolution needs two finite-time input sequences, but in the actual application, two infi-
nite-time input sequences are possible. Under this kind of situation, the partition convolution is an effective solu-
tion. In this paper, two methods of the partition convolution are discussed. The simulation experiment indicatesthat the partition convolution is correct and effective.)
