A simple adaptive up-link power control algorithm for DS/CDMA system

Power control is a fundamental process in direct sequence coded-division multiple-access (DS/CDMA) system. A proper algorithm must be employed on both the transmitter and receiver to mitigate near-far problem and prevent fading while maintaining sufficient transmission quality. This paper presents a simple adaptive up-link power control algorithm with simple yet effective features implemented on mobile handsets as well as on base stations. Simulation results show the improved performance of the proposed algorithm over current fast feedback closed-loop power control (FPC) algorithm.
