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.
