Abstract :
The capacity and the interference statistics of the sectors of the cigar-shaped W-CDMA microcell are studied. A model of multimicrocells is used to analyze the uplink when the users are within an under-ground train. The microcells are assumed to exist in a long under-ground tunnel. The capacity and the interference statistics of the microcells are studied for different propagation exponent, different antenna side lobe levels and different bends loss. The capacity for the best case and worst case are given.
