This paper proposes an analytical study which aims at evaluating the received power statistics in DS-CDMA cellular systems which use a closed-loop power control scheme to compensate for fast multipath fading. The effects of a limited transmission power at the mobile terminals have been also investigated. This study is based on a first order Taylor expansion of the fast fading fluctuations. The accuracy of the obtained results has been verified through computer simulations. Classical frequency-selective channel models have been taken into account which involve the use of a diversity RAKE receiver at the base station. Finally, the system capacity is evaluated under different environmental conditions.

Abstract

This paper proposes an analytical study which aims at evaluating the received power statistics in DS-CDMA cellular systems which use a closed-loop power control scheme to compensate for fast multipath fading. The effects of a limited transmission power at the mobile terminals have been also investigated. This study is based on a first order Taylor expansion of the fast fading fluctuations. The accuracy of the obtained results has been verified through computer simulations. Classical frequency-selective channel models have been taken into account which involve the use of a diversity RAKE receiver at the base station. Finally, the system capacity is evaluated under different environmental conditions.
