On the Capacity of Bidirectional Broadcast Channels under Channel Uncertainty
We consider the broadcast phase of a spectrally efficient two-phase decode-and-forward protocol which is used by a relay node to establish a bidirectional communication between two...

Gaussian Broadcast Channels with an Orthogonal and Bidirectional Cooperation Link
This paper considers a system where one transmitter broadcasts a single common message to two receivers linked by a bidirectional cooperation channel, which is assumed to be ortho...
