A novel interference cancellation detector, which combines an initial phase of cancelling one or more users per iteration depending on the tentative decision metrics, followed by maximum likelihood detection for the last few users, is proposed for multi-carrier CDMA uplink communication. Simulation results compare the system with a number of other multi-user detection receivers for an uplink multipath multi-user problem. The number of iterations and computation complexity are compared with a successive interference cancellation approach. The influence of the near–far effect and of poor channel estimation is also investigated.
