Abstract
Iterative multi-user detection with channel decoding is applied to MC-CDMA, the multi-user detector is implemented as successive interference canceller with post-minimum mean squared error filtering. A new channel estimation approach based on expectation maximization algorithm is proposed for the iterative detection. The proposed approach decreases the complexity of computation. Simulation shows that the proposed receiver approach single-user performance at very high channel load.
