WCDMA Multiservice Uplink Capacity of Highways Cigar-Shaped Microcells

Abstract

The multiservice uplink capacity and the interference (intracellular and intercellular) statistics (mean and variance) of the sectors of cigar-shaped wideband code-division multiple access (WCDMA) microcell are studied using a model of 5 highway microcells in rural zone. The two-slope propagation loss model with lognormal shadowing is used in the analysis. The capacity and the interference statistics of the microcell are studied for different sector ranges, antenna side lobe levels, standard deviation of the power control error, breakpoint distance, and different intersites correlation coefficient. It is shown that reducing the antenna side lobe level increases the sector capacity. Also, it is shown that the sector range that gives the quasi the maximum sector capacity is in the order of 800 to 1200 m.

WCDMA multiservice uplink capacity of highways cigar-shaped microcells with adjacent channel interference

“…1 and 2 represent the effect of shadowing (loss deviation from the mean value). Practical values of 1 , 2 , 1 , 2 and R b are [9] as follows: Figure 1 shows the sector's antenna azimuth radiation pattern and the microcell azimuth coverage. In [9], it has been shown that a model of only five microcells is sufficient for the uplink capacity analysis.…”

“…They have concluded that the twoslope propagation model is the most adequate to be used in the study of the microcells capacity. In [9], the WCDMA multiservice uplink capacity of highways cigar-shaped microcells has been given. The effect of the expected value and the variance of the multi-user interference have been used in the analysis.…”

“…The main contribution of this work is the extension of the results presented in [9] taking into account the impact of the ACI on the uplink capacity.…”

WCDMA Uplink Capacity of a Long Tunnel Cigar-shaped Microcells for Underground Train Service

“…In [9], the W-CDMA uplink practical capacity and interference statistics of rural highways cigar-shaped microcells with imperfect power control and finite transmitted power have been given where the two-slope model of propagation has been used to calculate the propagation loss. In [10], the WCDMA multiservice (voice and data) uplink capacity of highways cigar-shaped microcells has been studied.…”

Multipath Effect on the WCDMA Uplink Capacity of Highways Cigar-Shaped Microcells with Users within Cars and Buses

“…In [7], the W-CDMA uplink capacity and interference statistics of rural highways cigar-shaped microcells with imperfect power control and uniform distribution of users were obtained. In [8] which represent one of the newest works in this area, the WCDMA multiservice uplink capacity of highways cigar-shaped microcells has been given assuming simultaneous voice and data services. The WCDMA uplink capacity and interference statistics of highways shaped microcells with imperfect power control and finite transmitted power have been presented in [9].…”
