Transport of scalable video over CDMA wireless networks: A joint source coding and power control approach

We investigate the transport of scalable digital video over future third-generation (3G) wireless CDMA cellular systems. By considering the resource requirements as the aggregate of the products of source coding rates and the energy per information bit to noise ratio, we propose a joint source coding and power control (JSCPC) scheme which simultaneously maximizes the quality of the delivered video while minimizing the total resource consumption. We demonstrate the efficacy of this approach using the ITU-T H.263+ video source coder, although the approach is generally applicable to other source coding schemes as well.
