进入MatLab程序运行界面后，运行程序，界面会出现请输入NRZ玛，输入方式按数组方式输入，确认输入的NRZ码之后，程序会自动输出 CMI，AMI，HDB3的编码和解码的结果，可以清晰的对照出编码前后的结果。(into MatLab interface operating procedures, operating procedures, the interface will enter emerging NRZ Mary, by the array input mode input and confirm the NRZ, the program will automatically output CMI, AMI, HDB3 encoding and decoding, the results of which will clear up the control of the results before and after encoding.)

A major challenge to MIMO-OFDM systems is how to obtain the channel state in- formation accurately and promptly for coherent detection of information symbols and channel synchronization.

Chapter 4 - Forces and Moments

This function is for training a codebook for vector quantization. The data set is split to two clusters, first, and the mean of each cluster is found (centroids). The disttance of each vector from these centroids is found and each vector is associated with a cluster. The mean of vectors of each cluster replaces the centroid first. If the total distance is not improved substantially, The centroids are each split to two. This goes on untill the required number of clusters is reached and the improvement is not substantial.

说明：  matlab实现： ①用乘同余数法产生白噪声 ②遗忘因子递推最小二乘参数估计（FFRLS）③M序列及逆M序列的产生④批处理最小二乘参数估计（LS）⑤产生m序列(Use by remnant produce white noise with law )
