Abstract
The rate-distortion performance of a class of non-Gaussian source with memory is studied. The source model is generated from a correlated Gaussian source through a memoryless transform, which actually constitutes a special class of the frequently-used Gibbs model in speech and image processing applications. Its entropy and a rate-distortion bound are evaluated to obtain further insights into this class of source models. Several examples are also given to illustrate the usefulness and tightness of the rate-distortion bound
