Abstract

This paper combines multiuser detection and multicarrier signaling technique for direct sequence code division multiple access system (DS/CDMA). These techniques are analyzed in multipath fading environment. The receiver provides a decorrelating detector for each carrier and the outputs of the correlators are combined with a maximal-ratio combiner. The system performance is evaluated over Nakagami fading channels in the presence of partial band interference with numerical method. The system performance of multiuser detection combining multi-carrier DS/CDMA with the conventional single-carrier decorrelating detector was also compared.
