Abstract :
In this paper, we present numerical results to show the performance of power control (PC) by using antenna arrays at the base station (BS). We show that the diversity generated by antenna array, decreases the outage probability, the bit error rate (BER), the fluctuations of the received signal to interference ratio (SIR) over the target SIR, the transmitted power level, and finally increases the speed of convergence of power control algorithms in compared without diversity. These results also increase the system capacity and the quality of service (QoS).
