Abstract

In this work we consider the problem of combined source-channel coding for H.263 coded video transmitted over a wireless channel modeled as a slow-fading Rician channel. We use non-binary bandwidth-efficient trellis-coded modulation (TCM) employing appropriate phase-shift keyed modulation, and determine the optimal tradeoff between source and channel coding for the Rician channel as a function of the specular-to-diffuse energy ratio and the channel SNR. We show that if feedback on channel parameters is available, the video information can be optimally coded according to channel characteristics
