Abstract

In this paper, we establish a system model, including shadowing, multipath fading, antenna diversity and voice active factor, to estimate the system performance with considerations of the perfect and imperfect power control by using outage probability. Based on our calculations, it is shown that the system performance is sensitive to multipath fading, antenna diversity, and the power-control error. From our simulation results, three schemes are derived as follows: (1) The average power control is not powerful enough to maintain a minimum required number of subscribers per cell in fading environment or imperfect conditions; (2) Antenna diversity can be used to improve the system capacity in all conditions, not only considerations with the perfect power control, but also with the imperfect power control; (3) The system capacity is decreased rapidly by multipath fading and the power-control error.
