In this paper, the problem of power control in wireless systems using a distributed approach is analyzed. The uplink of a direct-sequence code-division multiple-access communication (DS-CDMA) system is studied in this work. The power control strategies are derived using classical design approaches (PID and dead-beat). It is concluded that the uplink channel variations do not destroy the stability...
One practical constraint imposed on closed-loop power control algorithms for a direct-sequence code-division multiple-access communication (DS-CDMA) system is the limited amount of feedback information. This paper proposes a closed-loop power control scheme with adaptive quantization on the basis of the number of power command bits. Adaptive quantization is used on the hypothesis that the quantization...
