Abstract

Aiming at the question of interference regeneration with small spread factors for frequency selective Rayleigh fading CDMA systems, we propose a concept of attenuation factors and a novel scheme of multistage nonlinear parallel interference cancellation (PIC) based on attenuation factors. Moreover, we analyze the effects of the attenuation factors of multistage non-linear PIC with small spread factors. Computation results show to what extent the performance can be improved
