这是一个bpsk的循环谱程序，实现了bpsk的三维循环谱图，自己写的，希望对大家有帮助。-his is a loop BPSK spectrum program, realized the 3 d of BPSK cyclic spectrum diagram, write their own, I hope it can help you.

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
