Abstract

In this paper, we propose an approach to solve the power allocation issues in a DS-CDMA cellular system using genetic algorithms (GAs). The transmitter power control has proven to be an efficient method to control cochannel interference in cellular PCS, increase bandwidth utilization and balance the wireless services. Most of the previous studies have assumed that the transmitter power level is controlled in a constant domain under the assumption of uniform distribution of users in the coverage area or in a continuous domain. In this paper, the optimal Centralized Power Control (CPC) vector is characterized and its optimal solution for CPC is presented using GAs in a large scale DS-CDMA cellular system.
