Gold 码的自相关序列的生成器以及自相关序列的特性图方面的仿真-the auto-relation sequence generator of the Gold code

程序使用了自相关性和互相关性较好的gold码作为扩频序列，直扩，扩频增益设置为31，模拟用户数为4-Program uses a self-correlation and cross-correlation of the better gold code as spreading sequence, direct expansion, spreading gain is set to 31 to simulate the number of users of 4

抽取法产生m序列优选对，并产生与之对应的所有Gold序列；做出了Gold码的自相关与互相关函数；验证了Gold码的个数-Extraction method m sequence pairs, and generate the corresponding Gold sequence to make a Gold code autocorrelation and cross correlation function to verify the number of Gold codes

通信工程中m序列编码，自相关，互相关计算,组合码的产生,GOLD码的产生-Communication Engineering in m-sequences encoding autocorrelation, cross-correlation calculations, produce a combined code, GOLD code generation

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
