Abstract :
Multi-cell CDMA systems with interference cancellation and powerful single-user channel coding close to the channel capacity are investigated for randomly chosen signature sequences and single cell site processing. Due to path loss and shadowing they show superior power and bandwidth efficiency on the AWGN channel compared with orthogonal multiple access. Moreover, attenuation controlled handover turns out to be significantly preferable in comparison with distance controlled handover if shadowing to different cell-sites is correlated
