Abstract

We consider a matrix algebraic approach to describe the multi-carrier CDMA (MC-CDMA) system with forward error control coding. We consider the uplink of a mobile communications system and derive the frequency selective channel model and show its similarity with the DS-CDMA channel. We therefore take advantage of a previously published technique that combines iterative decoding and interference cancellation to reduce the multiuser interference (MUI) present in the system and show that the performance approaches single user performance even for moderate signal to noise ratios
