GSM和QUALCOMM　CDMA系统信号设计方案的分析和比较

Anallysis and Comparison of Signal Design Schemes for GSM and Qualcomm CDMA Systems

ＴＤＭＡ和ＣＤＭＡ方式是当前数字移动通信中的两大主流。本文以其各自的典型系统（即泛欧的数字蜂窝移动通信系统ＧＳＭ和Ｑｕａｌｃｏｍｒｎ公司的ＣＤＭＡ系统）为例，分别对它们的信号设计方案进行了分析和比较，井从中反映出了两个系统各自的特点和共同之处。

TDMA and CDMA are the two main subjects in digital mobile communications. In this paper,we instance repective typical system(i.e.the Pan-European digital cellular system GSM and Qualcommcompany CDMA system),ttheir signal desig schemes are analysed and compared separstely ,from which the characteristic and generality design schemes are analysed and compared separstely,from which
