A Modified Parallel Interference Canceller in MC-CDMA uplink systems

Abstract

In the MC-CDMA uplink system, the user signal experiences different fading, suffering from a large amount of interference from other users. For reliable data detection, the use of multi user detector (MUD) with high complexity has been considered in the MC-CDMA uplink system. In this paper, we propose a modified parallel interference cancellation scheme (MPIC) that can provide the performance better than conventional MUD, while requiring affordable complexity.
