Abstract :
Based on the CMA, a proved blind multiuser detection, which combined with the multistage wiener filter(MSWF) for UWB systems in a realistic indoor channel is proposed in this paper. This new algorithm had a low computational complexity without the computation of matrix inverse. The proposed MSWF+CMA receiver is shown to have simpler computational complexity per weight update and faster convergence speed. Computer simulations show that, the proposed detector achieves good performances.
