Abstract
In this paper turbo multi-user detection (MUD) technique is proposed for multi carrier code division multiple access (MC-CDMA) system to overcome the affects of multiple access interference (MAI) caused by the inter-cell and intra-cell interference and near far effect. The proposed technique estimates the interference from the unknown users and the interference estimate is subtracted from the received signal. Simulation results show that the turbo multi user detector significantly outperforms the conventional multi user detector for moderate and high signal-to-noise ratios.
