| 摘 要： | 本文将多重ＴＣＭ技术应用于室内慢衰落信道下的直接序列扩频多址（ＤＳ／ＳＳＭＡ）系统中，提出了一种发射端和接收端分别采用多重伪码扩频和多重相关接收的ＤＳ／ＳＳＭＡ系统模型及其理论分析方法。在系统用户数、用户信源比特速率和伪码周期相同的条件下，模拟结果表明采用多重ＴＣＭ的ＤＳ／ＳＳＭＡ系统性能显著优于一重ＴＣＭＤＳ／ＳＳＭＡ系统的性能

| Abstract: | In this paper multidimensional trellis coded modulation(multi DTCM)is applied to direct sequence spread spectrum multiple access system in slow fading channel.We propose a model of DS/SSMA system using multi spread spectrum and multi correlation reception at transmitter and receiver respectively and the way for theoretical analysis of them.The simulation result shows that the performance of multi D TCM DS/SSMA system is far better than that of TCM DS/SSMA systems. |
