Abstract :
In this paper, we extend the setting of source coding with successive refinement into a joint source-channel coding setting: two descriptions of a memoryless source are to be transmitted across two independent memoryless channels. The output of the channel corresponding to the first (coarse) description is also available to the decoder of the second (refinement) channel. Side information (SI) is available to the decoders. Feedback from the output of the first (coarse) channel to the encoder of the second (refinement) channel is also available
