Abstract :
Layered space-time architecture can achieve high channel capacity by deploying multiple transmit and receive antennas, but the existence of inter-symbol interference (ISI) and co-channel interference (CCI) limits its performance over frequency selective fading channels. In this paper, a new adaptive equalization with interference cancellation method based on affine projection algorithm (APA) is developed. The proposed algorithm performs interference cancellation in the process of detection without channel identification. Simulation results demonstrate the promising performance of the proposed method. Furthermore, this algorithm can obtain significant computation saving over the existed RLS-IC-DFE algorithm with approximately the same bit error rate (BER) performance
