High-resolution predictive Wyner-Ziv coding of Gaussian sources

A predictive scheme for zero-delay Wyner-Ziv coding of sources with memory is proposed and analyzed in the high-resolution regime for Gaussian source-side information pairs. Incorporating the propagation of distortion due to occasional decoding errors into the analysis, the quantizers and first-order filter parameters are simultaneously optimized. The rate-distortion performance of the scheme is compared with those of non-distributed coding and Wyner-Ziv coding with a naive choice of prediction filters (minimizing temporal correlation), as well as the asymptotic Wyner-Ziv rate-distortion function.
