• An effective transmitter power control method is indispensable in combating the near-far problem and minimizing the effect of interference on the system capacity. This paper investigates the power control problem for the uplink direct sequence-code division multiple access (DS-CDMA) system. In recent works on power control problem, power levels are assumed to take on any positive real value. However, in practical systems, power levels are discrete. This paper therefore proposes a power control algorithm over a discrete set of power levels in which each base station locally optimizes the power set of all users in its own cell. Also, we investigate its convergence and power consumption properties. Simulation results indicate that the proposed power control algorithm converges faster and provides an improved performance.
