Abstract :
The rate region of the two-terminal vector Gaussian CEO problem is studied. A lower bound on the rate region is derived. It is obtained by lower-bounding a weighted sum rate for each supporting hyper plane of the rate region. The bound is in the form of a closed-form expression rather than the form of an optimization problem.
