Description: 以往扩频通信系统不同，本文用序列偶代替Gold码应用于扩频通信系统。随着CDMA通信系统的应用
范围越来越广泛，目前可用的地址码的数量有限并且码长均有限，这样就给实际工程带来很大的不便。本文首先介绍
了序列偶的概念和几种重要的盲多用户检测方法。再将满足一定条件的序列偶应用于盲多用户检测中，通过理论分
析和实验仿真，证明了序列偶应用于扩频通信系统的可行性。因此序列偶能很好的弥补目前扩频码存在的数量有限
的缺陷，作为现有扩频码的有效补充。-Different from early spread communication system，this text uses sequence pairs substitute Gold．Along with
CDMA communicatiofi system widely used，and the number and length of address code are both limited，it is
inconvenient tO apply in practice．Sequence pairs and some of important blind multiuser detections are discussed．Then
the sequence pairs which satisfy the certain given eonditions are applied to blind MUD．Through theoretical analysis and
experimental simulation，the feasibility of sequence pairs being applied tO spread spectrum system is proved．So sequence
pairs can remedY the number restriction of spread spectrum code and supply it well

Description: Gold code sequence generator
Run from editor Debug (F5)
JC 4/25/09
Gold code generation can sometimes be confusing and hopefully this m-file
will be helpful. The m-file uses two preferred pairs of m-sequences (length 2^n-1)
chips long where n=5 with length 31. The 33 gold codes
(two original m-sequences plus 2^n-1 gold codes) produced in a 31x33 matrix
here (with n=5) are probably not to useful for multiple access situations (CDMA)
but is used here to provide a model for learning. The preferred pair used
here is 52 and 5432 or 45 and 75 octal. Other preferred pairs can include values
such as 53 5321, 5431, and 5421. The m-file will also check the cross-correlation
values between any two codes in the matrix and should be three valued (-9,-1,7). The
autocorrelation of a Gold code can also be checked. Some, not all, of the
Gold codes in the matrix are balanced (16 1 s and 15 -1 s).
