Abstract— The cognitive radio channel (CRC) refers to a communication model in which two senders attempt to communicate with their respective receivers simultaneously through a c...
We investigate the effects of user cooperation on the secrecy of broadcast channels by considering a cooperative relay broadcast channel. We show that user cooperation can increase...
An achievable rate region for line networks with edge and node capacity constraints and broadcasting is derived. The region is the capacity region if the broadcast channels are ort...

We consider the joint source-channel coding problem of sending a Gaussian source over a K-user Gaussian broadcast channel with bandwidth mismatch. A new outer bound to the achieva...
This paper considers the problem of the multiple-input multiple-output (MIMO) Gaussian broadcast channel with two receivers (receivers 1 and 2) and two messages: a common message ...
