【Abstract】 By comparing several methods of soft-decision, this article put forward a scheme of the parallel interference cancellation (PIC) with simplified firt-order self-regression weighted soft-decision and its range of selecting the optimum weighted factor. Simulation results show that the performance of the PIC system is superior to that of the others.更多还原
