Joint source-channel coding for scalable video over DS-CDMA multipath fading channels

In this paper, we extend our previous work onjoint source-channel coding to scalablevideo transmissionover wireless direct-sequence code-division-multiple-access(DS-CDMA)multipath fadingchannels. An SNR scalable video coder is used and unequal.error protection (UEP) is allowed for each scalable layer. At the reveiverend an adaptive antenna array Auxiliary-Vector (AV) filter is utilized that provides space-timeRAKE-type processingand multipleaccess interference suppression. The choice of the AV receiver is dictated by realistic channel fading rates that limit the data record available for receiver adaptation and redesign. Our problem is to allocate the available bit rate of the user of interest between source and channel coding and across scalable layers, while minimizing the end-to-end distortion of the received video sequence. The optimizationalgorithmthat we propose utilizes universal ratedistortion characteristic (curvesthat show the contribution of each layer to the total distorti...
