BCH编解码，能显示编译前后的码型变换，成功运行(BCH codecs, can show a pattern transformation compiled before and after successful operation)

16qam的OFDM调制与解调，对ofdm信号的产生过程详细介绍，包含星座图(16QAM OFDM modulation and demodulation, ofdm signal generation process is described in detail, contains the constellation of FIG.)

estimate offset time for pulse that modulate in bpsk and compare pe to snr with without offset . we assume offset is between 0 to 4

说明：  神经网络的计算，包括训练和测试两部分，利用的是最小均方误差算法。(Nerual network calculation,including training and working part,utilizing MMSE algorithm.)

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)
