• The performance of a cellular CDMA system operating over a flat-Rayleigh fading channel was previously considered, where it was assumed that the coherent bandwidth of a channel exceeded the spread bandwidth of a signal. This assumption may not be correct for a large degree of spreading. Therefore, the channel is modeled as exhibiting frequency-selectivity. In this paper, we consider a cellular radio DS/CDMA system operating over a frequency-selective fading channel. The base-to-mobile link is modeled as a Rician fading channel, with all signals transmitted from a given base station fading in unison. A similar model for the mobile-to-base link is used, except that the waveforms from all users are assumed to experience independent fading. The capacity of the cellular radio DS/CDMA system operating over a frequency-selective fading channel is evaluated and compared to that over a flat Rayleigh fading channel.
