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.
