Abstract

This paper presents a performance analysis of a multimedia DS/CDMA system based on different error control schemes and an optimal power control algorithm for wireless personal communication services. The error control schemes consist of Forward Error Correction (FEC), diversity and Automatic Repeat reQuest (ARQ). Since a multimedia system is required to support services with different rates and Quality of Services (QoS), different error control schemes are used to satisfy the requirements of different media. In particular, a power control algorithm which can optimize the capacity performance of the integrated system is presented. Numerical results over multipath Rayleigh fading channels will show that power optimization can increase the capacity and decrease the total transmission power in a multimedia CDMA system. By incorporating diversity and hybrid ARQ along with appropriate coding rates in the optimal power controlled system, dramatic increase in system capacity can also be achieved.
