Joint source-channel decoding of JPEG images using error resilient source codes
W. Xiang, Steven S. Pietrobon, S.A. Barbulescu · 2003
Iterative decoding of JPEG images does not perform well due to the poor distance property of the original JPEG Huffman codes. We propose a symmetric RVLC with large free distance which can dramatically improve the system performance when iterative decoding is performed. Simulation results indicate up to 4 dB coding gain is achievable.
