Abstract :
We derive a lower bound on each supporting hyperplane of the rate region of the vector Gaussian multiterminal source coding problem by coupling it with the CEO problem through a limiting argument. The tightness of this lower bound in the high-resolution regime and the weak-dependence regime is proved.
