An uplink power control scheme in CDMA mobile communication system

In this paper, a brief introduction of principles and algorithm realization of uplink power control in CDMA mobile communication system based on IS-95 are given, and then the blocking probability and Erlang capacity under the condition of perfect and imperfect uplink power control are presented and analyzed. Finally the uplink power control algorithms are simulated, and the optimum uplink power control algorithm that maximizes system Erlang capacity is acquired.
