Abstract

Performance analysis is carried out for a cluster of a M-ary orthogonal DS/CDMA cellular system. The bit error rate (BER) is evaluated for both the forward and the reverse link, considering a wideband frequency selective channel with Rayleigh fading and lognormal shadowing. Both cases of power control (perfect and imperfect) within each cell are examined. Coherent and noncoherent RAKE receivers are studied for the forward and the reverse link, respectively, through appropriate numerical techniques calculating the target integrals. Owing to the channel model complexity, an equivalent lognormal distribution has to be introduced to make the calculations more convenient. An increased user accommodation capability, in comparison with the one cell study, results from the overall analysis of the system
