Lossy source coding for a cascade communication system with side-informations. Vasudevan, D., C.Tian, & Diggavi, S N. In Proceedings of Allerton Conference on Communication, Control, and Computing, Illinois, September, 2006.
abstract   bibtex   
We investigate source coding in a cascade communication system consisting of an encoder, a relay and an end terminal, where both the relay and the end terminal wish to reconstruct source X with certain fidelities. Additionally, side-informations Z and Y are available at the relay and the end terminal, respectively. The side-information Z at the relay is a physically degraded version of side-information Y at the end terminal. We give an exact characterization for the Gaussian quadratic distortion version of the problem and develop inner and outer bounds for the general case.
