Abstract :
In this paper, we propose a multiuser detection (MUD) scheme based on co-channel interference cancellation for a slow frequency-hopping multiple-access system. The error performance of the SFHMA system with the proposed MUD scheme is investigated over the interference-only channel. Both analytical and simulation results are presented, and it is shown that the MUD algorithm can improve system performance considerably.
