Description: 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 wireless communication technology developed on the branch of digital technology, spread spectrum communication technology. The principle of CDMA technology is based on spread spectrum technology, which uses a high-speed pseudo-random code whose bandwidth is much larger than the signal bandwidth to modulate the data which needs to be transmitted, so that the bandwidth of the original data signal can be expanded, and then modulated by carrier wave and sent out.)
