跳频/多载波频率分集/扩频多址无线通信系统的研究

本文提出了一种跳频／多载波频率分集／扩频多址（ＦＨ／ＭＣＦＤ／ＳＳＭＡ）无线通信系统，给出了ＦＨ／ＭＣＦＤ／ＳＳＭＡ系统的发送和接收模型，对判惟变量统计特性进行了分析，然后对峰窝系统反向链路在理想定时和信道估计条件下用户平均接收误码率进行了仿真。结果表明，ＦＨ／ＭＣＦＤ／ＳＳＭＡ蜂窝通信系统具有较好的抗多径衰落能力，同单载波ＦＨ／ＳＳＭＡ系统相比其误码性能和频谱效率有显著改善。

The study of FH/MCFD/SSMA wireless communication systems

A scheme of frequency hopping/multiple carrier frequency diversity/spread spectrum multiple access(FH/MCFD/SSMA)wireless communication system is proposed in this paper The transmitter and receiver models of FH/MCFD/SSMA systems is presented first,then the stochastic characteristics of decision variable is analyzed,and the bit error performance in reverse links of cellular systems is simulated assuming that ideal channel estimation and symbol timing can be obtained The simulation results shows that FH/MCFD/SSMA is effective to less multi path fading,and the BER performance and spectrum efficiency can be improved greatly compared with single carrier FH/SSMA systems
