刻画随机过程X(t)在各个独立时刻的概率统计特性,反映不了随机过程的内在相关性(Characterize the probability statistical properties of stochastic process X (t) at each independent moment, which can not reflect the inherent correlation of stochastic process)

MATLAB代码生成Gold码、m序列并得到自相关、互相关函数。之后进行BPSK调制，验证扩频通信的错码率的降低。(Gold code and m sequence are generated and autocorrelation and cross-correlation functions are obtained. Then BPSK modulation is carried out to verify the reduction of error rate of spread spe
