摘要 正交多载波码分多址(MC-CDMA)是近年来无线通信研究的热点。本文介绍了MC-CDMA系统的多用户检测技术,分析了与直接序列(DS-CDMA)系统的对偶性关系,并通过将两种系统的多用户检测算法分类比较,指出将DS-CDMA的多用户检测算法引入到MC-CDMA中的可行性,讨论了MC-CDMA多用户检测的发展方向。 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 analyze the duality between MC- CDMA and Direct Sequence (DS -CDMA). Moreover, by comparing Multi -User Detection (MUD) techniques in the two systems,we point out the necessity of introducing MUD techniques into MC -CDMA,in the end, we discuss the future development of MC -CDMA MUD.
