• In this paper, a hybrid FDMA/CDMA system and a wideband CDMA (W-CDMA) system in the frequency selective Rayleigh fading are considered. The bit error rate (BER) and coded symbol error rate performance of a coherent BPSK RAKE receiver under the various number of receiver fingers are derived and evaluated. In addition, a multiple access control (MAC) protocol based on packet-switched network is proposed and computer simulation is performed. Then, the results of performance evaluation are compared. The numerical analysis shows that the performance of the hybrid system is better than that of the W-CDMA in situation when the RAKE receiver complexities are kept constant in both systems. As noted, when each system has as many fingers as paths, the performance of the full-fingered W-CDMA is best. The 2- or 3-subspectrum FCDMA, however, has almost the same performance compared with the full-fingered W-CDMA when we applied the proposed MAC protocol to the system.
