Distributed joint source-channel arithmetic coding
We deal with the problem of distributed source coding with decoder side information, when the decoder observes the source through a noisy channel. Existing approaches employ syndr...

Performance Bounds and Distance Spectra of Variable Length Codes in Turbo/Concatenated Systems
Abstract--Variable length codes (VLCs), used in data compression, are very sensitive to error propagation in the presence of noisy channels. Addressing this problem with joint sour...
