The Capacity Region of a Product of Two Unmatched Physically Degraded Gaussian Broadcast Channels with Three Individual Messages and a Common Message
Abstract
This paper considers a Gaussian broadcast channel with two unmatched degraded components, three individual messages, and a common message that is intended for all three receivers. It is shown that for this channel, superposition coding with Gaussian signalling is sufficient to achieve every point in the capacity region.
