Abstract :
In this paper we present a channel-optimized video transmission (COVT) scheme over WCDMA system. Specifically, the video encoder is composed of multiple descriptions coding (MDC) and layered coding (LC). This hybrid video encoder features that one description of MDC. is compatible with the base layer coder of the LC. The COVT system is designed to provide high quality video in case of no channel fading, and acceptable quality while in deep and long fading. Simulation results confirm that the COVT scheme outperforms traditional source-channel independent transmission system remarkably for the time-varying mobile channels.
