Partial weight multistage interference cancellation for reverse link MC-CDMA system using pilot assisted channel estimation

We propose a partial weight multistage interference cancellation (PWM-IC) technique to enhance the performance of the reverse link of a multicarrier code division multiple access (MC-CDMA) system. The performance of our proposed receiver, as well as other multiuser detection techniques, is evaluated in a time varying Rayleigh multipath channel by computer simulation. We also consider the impact of the channel estimation error on the performance of each receiver. Channel parameters are obtained using pilot symbols.
