Abstract:

We consider the separate source coding problem of L correlated Gaussian observations Yi, i = 1, 2, …, L. We consider the case that Yi, i = 1, 2, …, L satisfy Yi = Xi+Ni, i = 1, 2, … , L where Xi, i = 1, 2, …, L are L correlated Gaussian random variables and Ni, i = 1, 2, … L are independent additive Gaussian noises also independent of Xi, i = 1, 2, …, L. On this coding system the determination problem of the rate distortion region remains open. In our previous works, we derived explicit outer and inner bounds of the rate distortion region and sufficient condition for the inner and outer bounds to match. In this paper we derive a stronger sufficient condition for those two bounds to match.
