Abstract

The performance of a multicell DS-CDMA cellular system with base station diversity is studied taking into consideration the effects of imperfect power control, multipath fading, shadowing and the dependence of propagation losses to a different base station from a mobile user. It is assumed that a mobile user is connected to the base station that provides the least attenuation among a set of closest uniformly correlated base stations. Analytical expressions are derived for the average probability of error of binary phase shift keying modulated signals for both the reverse link and the forward link. The channel is assumed to undergo correlated lognormal shadowed Rayleigh fading. Analytical results show that base station diversity significantly improves system performance
