title = "Coded wireless video broadcast/ multicast: A cross-layer framework and end-to-end distortion analysis",
abstract = "A cross-layer framework of interplay between multiple description coding (MDC) at the source and layered modulation using superposition coding (SPC) at the channel has recently been proposed as an effective approach to mitigate the vicious effects due to multi-user diversity and fast Rayleigh fading in wireless video broadcast/ multicast. However, there has not been a rigorous and general end-to-end distortion analysis to determine if and when such interplay between the protection code (such as MDC) in the upper layer and the multi-resolution modulation by way of SPC in PHY/MAC layer for transmitting successively refined information can lead to a better end-to-end distortion performance than other possibilities. The paper provides a comprehensive information theoretical analysis on the end-to-end distortion. Mathematical proofs are derived to confirm the advantages and conditions of such cross-layer systems to always give the better distortion performance. Numerical analysis is conducted to verify the mathematical conclusions while unveiling some interesting observations.",
