摘要

正交多载波码分多址(MC-CDMA)是近年无线宽带通信研究的热点.本文介绍了MC-CDMA信号检测技术

在分析频率选择性衰落信道中单小区MC-CDMA系统上/下行多址干扰(MAI)的基础上

指出上行接收引入多用户检测技术(MuD)的必要性和可能性

并通过与直接序列(DS)CDMA的对照和对偶性分析

讨论了MC-CDMA MuD的发展方向.

Abstract

Orthogonal Multi-carrier Code Division Multiple Access (MC-CDMA) has attracted much attention in recent years.In this paper

an overview of MC-CDMA detection techniques is presented

and we point out the necessity and possibility of introducing multi-user detection (MuD) techniques into MC-CDMA uplink reception

based on an analysis of the Multiple Access Interference (MAI) in both uplink and downlink.Moreover

by comparing Direct Sequence (DS) CDMA and MC-CDMA and analyzing the duality between them

we discuss the future development of MC-CDMA MuD.
