In this paper, based on the theory of multicarrier（MC） signaling technique and the RAKE receiver, a multicarrier DS-CDMA RAKE system is proposed. We evaluate the system performance over Rayleigh fading channel with multiple access interference（MAI） and narrow-band interference（NBI） present, and compare the results with those of both a single carrier RAKE system and a multicarrier DS CDMA system. It is shown from the simulation results that the presented model has larger capability of suppressing narrow-band interference and multiple-acces...
