由于MATLAB本身自带的相关函数在扩频通信中并不适合，性能欠佳。本程序是我自己编写的求自相关或互相关的MATLAB函数。可直接调用该函数。已通过验证。-The poor performance is not suitable for the correlation function in a spread spectrum communication MATLAB comes. This program is my own written demand autocorrelation or cross-correlation function of MATLAB. This function can be called directly. Has been verified.
