摘要

在直接序列扩频通信（ＤＳ／ＣＤＭＡ）系统中，为了有效地实现用户高数据率的传输，以适应宽带ＣＤＭＡ技术发展的要求，本文提出了一种双正交多码ＣＤＭＡ系统（称为ＢＭＣＣＤＭＡ）．相似于多载波调制，传输的高数据率首先进行串并转换，然后对变换后的低数据流用双正交码进行扩频调制．不同于多载波调制，各支路扩频信号用同一载波进行调制．并对此系统在衰落信道的性能进行了计算，还对数值结果进行了分析．

Abstract

In this paper

a biorthogonal multicode CDMA system （called BMC CDMA） is proposed so as to transmit higher rate data to fit the requirement of technical development of wide band CDMA system.Similar to multicarrier modulation

the higher rate data are transmitted at first by serial to parallel conversion

then the lower rate data streams are spreaded in spectrum by a set of biothogonal code.Being different from multicarrier modulation

all lower branch data streams use a single carrier.The performance of the system in fading channel is calulated

and numerical result is analyzed.
