Recent studies have indicated a cross-layer design approach that supports multiple protocol layer adaptivity and optimization can yield significant performance gains. This paper investigates some of these issues for the end-to-end transport of packetized digital video over CDMA networks. The paper studies a problem in cross-layer adaptation and optimization for multimedia delivery over IP-based CDMA cellular networks. By considering the resource requirements as the aggregate of the products of source coding rates and the energy per information bit to noise ratio, the paper proposes a Joint Source Coding-Power Control (JSCPC) strategy combined with Joint Source-Channel Coding (JSCC) to simultaneously maximize the quality of the delivered video while minimizing the total resource consumption.
