Dalam makalah ini, sistem FDMA/CDMA hibrid dan sistem CDMA (W-CDMA) jalur lebar dalam pudar Rayleigh terpilih frekuensi dipertimbangkan. Kadar ralat bit (BER) dan prestasi kadar ralat simbol berkod bagi penerima BPSK RAKE yang koheren di bawah pelbagai bilangan jari penerima diperoleh dan dinilai. Selain itu, protokol kawalan capaian berbilang (MAC) berdasarkan rangkaian bertukar paket dicadangkan dan simulasi komputer dilakukan. Kemudian, hasil penilaian prestasi dibandingkan. Analisis berangka menunjukkan bahawa prestasi sistem hibrid adalah lebih baik daripada W-CDMA dalam keadaan apabila kerumitan penerima RAKE dikekalkan malar dalam kedua-dua sistem. Seperti yang dinyatakan, apabila setiap sistem mempunyai seberapa banyak jari sebagai laluan, prestasi W-CDMA jari penuh adalah yang terbaik. FCDMA 2- atau 3-subspektrum, bagaimanapun, mempunyai prestasi yang hampir sama berbanding dengan W-CDMA jari penuh apabila kami menggunakan protokol MAC yang dicadangkan pada sistem.

Abstract: 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.
