Abstract

In this paper, the multiclass downlink capacity and the interference statistics of the sectors of a cigar-shaped microcells using wideband code-division multiple-access with soft handover mode are analyzed. The two-slope propagation model with log-normal shadowing is used in the analysis where a model of 8 cigar-shaped microcells is utilized. The performance of the downlink is studied for different [sector range R, standard deviation of the shadowing (\(\sigma _{1}\) and \(\sigma _{2})\) and propagation exponents (\(\text{ s}_{1}\) and \(\text{ s}_{2})\)]. It is found that increasing the sector range from 500 to 1,000 m will increase the sector downlink capacity. Also, it is found that increasing the value of the propagation parameters (\(\sigma _{1}\) and \(\sigma _{2})\) will reduce the downlink sector capacity. It is noticed that, the effect of changing the propagation exponent \(\text{ s}_{1}\) is null while increasing the propagation exponent \(\text{ s}_{2}\) will increase the downlink capacity.
