Asymmetric Gaussian Multiple Descriptions and Asymmetric Multilevel Diversity Coding

We consider multiple description source coding problem with Gaussian source and mean squared error, for $K=3$ descriptions. We obtain an outer bound for the rate region of the problem. We also derive an inner bound for the problem based on successively refineability of the Gaussian source and multi-level diversity coding. Our gap analysis shows that the difference between two bounds is less than $1.3$ bits, in the worst case.
