Paper Abstract

In this paper, we propose a new technique in direct sequence code division multiple access system using on-off key and modified prime sequence code, the scheme of this technique dubbed successive interference cancellation (SIC). The basic principle of SIC scheme is to subtract the strongest received signals from the original signal one by one till all users have been detected, and demodulated. In this analysis we take in account the possibilities of errors in previous cancellation. It has been shown that the proposal IC scheme with (-20dBm) effective power can suppress multiple-access interference (MAI), and improve the system performance significantly.
