Application of joint source-channel matching in heterogeneous multi-media environments will demand general source-channel optimization schemes suitable for a wide variety of source coding standards, channel coders, and variable channel conditions. We develop a general approach for joint source-channel matching based on a parametric distortion model that can be accurately applied to most classes...

By only sending the parity bits, joint source-channel coding can be natively achieved with lowdensity parity-check codes. However, the code ensemble design of optimal low-density parity-check codes for joint source-channel coding over asymmetric communication channels is difficult. To circumvent such a difficulty, source-channel adaptors is proposed in this paper. By using the source-channel ad...

The design of a low complexity joint source channel codec for images using trellis coded quantization and convolutional codes is studied. It is shown that a low complexity joint source channel codec offering high robustness is enabled by using the same Ungerboeck trellis code to do both quantization and convolutional coding. Simulation results are presented for joint source channel coding of Ga...
