Abstract:In this work we address the problem of transmission of a useful class of hidden Markov sources with Gaussian observations over a discrete-time power-constrained AWGN channel. Our source model approximates the wavelet representation of natural images, and is motivated by the recent successful modeling approaches in the state-of-the-art image compression and restoration methods. We derive information-theoretic performance bounds, and propose a simple yet efficient joint source-channel coding solution which combi… Show more
