Quantizer design with mismatched side information at the decoder
Quantizer design for lossy compression with mismatched side information (SI) at the decoder is investigated. The statistical dependency between the source and SI is assumed to be ...

Scalable predictive coding by nested quantization with layered side information
An efficient scalable predictive coding method is proposed for the Wyner-Ziv problem, using nested lattice quantization followed by multi-layer Slepian-Wolf coders (SWC) with laye...

Source Coding With Distortion Side Information
We analyze the impact of side information about the distortion measure in problems of quantization. We show that such "distortion side information" is not only useful at...

Practical codes for lossy compression when side information may be absent
Practical codes are developed for quadratic Gaussian lossy compression when side information may be absent by hybridizing successively refinable trellis coded quantization (SR-TC...

On Quantizer Design for Soft Values in the Multiple-Access Relay Channel
—A network with two sources, one relay, and one destination is considered. Under the assumption of noisy sourcerelay links causing the relay to be unable to decode without error,...
