N2 - The goal for the next generation of mobile communication systems is to seamlessly integrate a wide variety of communication services in addition to voice. MAI (Multiple Access Interference) is one of the important performance-limiting factors in a WCDMA system. In addition to this, the unreliable radio links further complicates this issue. Consequently, it is highly challenging to ensure guaranteed quality of service (QoS) requirements for the multi-service users. The unreliability of transmission medium is mainly due to time varying long term and short-term fading. Evidently, in order to combat adverse propagation conditions and interference, mobile radios can adapt various transmission controls like transmission power, source/channel codes, etc to meet the desired performance requirements. In this work, a link adaptive mechanism for WCDMA systems is proposed and analyzed. The proposed algorithm provides better system performance in terms of convergence time and power consumption than existing power control algorithms.
