In quadratic Gaussian multiple descriptions (MD) coding, an encoder may use common codewords shared by multiple descriptions, in addition to the refinement codebooks used to encode…

Let $D_k < 1-\frac{k}{n}$ be rational, and consider the erasure multiple descriptions problem with $k=2$ and $n>3$. Let $D_1^*$ denote the infimum single-message distortion among a…
