More accurate performance analysis of interference canceler in an asynchronous DS-CDMA system over the multipath fading channel

An accurate analytical method of an asynchronous direct sequence (DS) code division multiple access (CDMA) system using a interference cancellation (IC) technique is proposed. In this analysis, a RAKE receiver is considered over uplink fading channels that are modeled as slowly varying Rayleigh-fading discrete multi-path channels. By Monte Carlo simulations, it is shown that the proposed analysis is more exact to simulation results than the previous ones.
