Joint source-channel codec: a more power efficient technology for image transmission
Wei Xiang, Steven S. Pietrobon, Steven Barbulescu · 2003
Abstract: Huffman codes used in JPEG cod-ing are replaced with reversible variable-length codes (RVLCs) with larger free distance. The extra redun-dancy is used in a joint source-channel codec based on the state transition probabilities of the RVLC. After accounting for the penalty due to increased average codeword length, the RVLC scheme achieves a 4 dB gain over an equivalent turbo coded JPEG transmis-sion system1.
