Abstract :
In order to suppress the Multiple-Access Interference (MAI) in the DS CDMA system, a new RAKE receiver based on parallel interference elimination is proposed in this paper. The multiple-access interference is evaluated by known user information and tentative decision. Then the performance over Rayleigh fading channel are analyzed and compared to convention PIC receiver and PIC RAKE receiver. It is shown that RAKE receiver performance can be improved greatly by using Parallel Interference Cancellation (PIC) method with simple structure and easy implementation [1].
