Abstract :
In this paper, a new approach for multistage multiuser detection for asynchronous code division multiple access communications is proposed. It mainly consists of matched filtering and generalized multistage processing with a sliding window. Finally, its performance is verified by simulations in multipath Rayleigh fading channels. Comparisons of the performance between the new approach and the well-know parallel interference cancellation concept in different situations are illustrated
