Performance of MC-MFSK systems with IIC-based multiuser detection over Rayleigh fading channels

In this paper, we propose a multiuser detector (MUD) that is based on iterative interference cancellation (IIC), for a multiple-access multi-carrier M-ary frequency-shift-keying (MC-MFSK) system. We evaluate the error probability performance of this MC-MFSK system over Rayleigh fading channels, through both theoretical analyses and computer simulations. We show that the IIC-based MUD algorithm can be easily implemented and can improve system performance considerably.
