Abstract :
This paper presents a distributed power control scheme for third-generation wideband CDMA systems. In the algorithm, a kind of power update function of exponential type is presented. By adjusting parameter k in the power update function, the system can satisfy different performance requirements. Simulation results reveal that our algorithm has faster convergence speed and better system stability than the conventional distributed power control algorithm
