A LINEAR HYBRID MULTI-USER DETECTOR BASED ON SUCCESSIVE INTERFERENCE CANCELLATION AND DECORRELATOR DETECTOR FOR DS/CDMA SYSTEM

Abstract

A linear hybrid multi-user detector in synchronous direct sequence code division multiple access systems (DS/CDMA) is performed by using linear successive interference cancellation detector (SIC) and linear decorrelator detector in order to exploit the advantages offered by the two detectors. Its main objectives are to reduce the long detection delay times and to improve the performance compared to that of the conventional SIC. Finally, theoretical and simulation results are in perfect agreement demonstrating the effectiveness of the elaborated scheme.
