Abstract

This paper addresses uplink power control for terminals that transmit multimedia signals in a CDMA cell. The aim of the power control is to minimize total power consumed by the terminals due to signal compression and transmission while the end-to-end distortion for each terminal is kept at a predetermined value. We propose a distributed iterative power control algorithm and prove convergence. The simulations for Gauss-Markov source with transform coder and H.263 encoded video signal show that the proposed algorithm achieves the jointly optimal power values for most of the channel conditions. It is also observed that the algorithm outperforms non-adaptive multimedia transmission in terms of power consumption.
