伪随机序列、伪噪声(PN)码或伪随机码。可以预先确定并且可以重复实现的序列称为确定序列；既不能预先确定又不能重复实现的序列称随机序列；不能预先确定但可以重复产生的序列称伪随机序列。-Pseudo-random sequence, a pseudo noise (PN) code, or pseudo-random code. The sequence is called to determine the sequence can be pre-determined and can be repe

通过电原理图的方式，产生伪随机码序列，并附有原理说明-By electrical schematics, generate pseudo-random code

CDMA是码分多址的英文缩写(CodeDivisionMultipleAccess)，它是在数字技术的分支--扩频通信技术上发展起来的一种崭新而成熟的无线通信技术。CDMA技术的原理是基于扩频技术，即将需传送的具有一定信号带宽信息数据，用一个带宽远大于信号带宽的高速伪随机码进行调制，使原数据信号的带宽被扩展，再经载波调制并发送出去。(CDMA is the abbreviation of Code Division MultipleAccess. It is a new and mature w
