WCDMA multiclass downlink capacity and interference statistics of cigar-shaped microcells in highways

Abstract

The final publication is available at Springer via http://dx.doi.org/10.1007/s11277-013-1048-5In 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 (σ1 and σ2) and propagation exponents (s1 and s2)]. 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 (σ1 and σ2) will reduce the downlink sector capacity. It is noticed that, the effect of changing the propagation exponent s1 is null while increasing the propagation exponent s2 will increase the downlink capacit
