Abstract In this paper, the blind multiuser detector operating over multipath fading channel with high-power Narrow Bandwidth Interference (NBI) is presented. It has the basic structure of RAKE receiver in which every path signal could be traced by MMSE optimization strategy, therefore it can suppress the NBI and Multi-Access Interference (MAI) over multipath fading channel. It has been proved by the simulation results that the performance of the detector is superior to those without considering NBI suppression.
