The authors investigate the performance of hybrid direct sequence (DS) slow frequency hopped (SFH) spread spectrum multiple access communication systems over a Rayleigh multipath fading channel for indoor wireless communications. Systems with binary, M-ary frequency shift keying, as well as differential phase shift keying modulation and noncoherent demodulation, are studied. Their average error probabilities are analyzed for both deterministic and random frequency hopping pattern signature sequences. Numerical results show that the performance of the hybrid system degrades considerably over the multipath fading channel as compared to the nonfading channel. The system's performance degrades gracefully as the number of simultaneous users increases
