Dependence Balance Based Outer Bounds for Gaussian Networks with Cooperation and Feedback
We obtain new outer bounds on the capacity regions of the two-user multiple access channel with generalized feedback (MAC-GF) and the two-user interference channel with generalize...

On the Capacity Region of the Gaussian Multiple Access Channel with Noisy Feedback
—We provide a new outer bound on the capacity region of the two-user Gaussian multiple access channel (MAC) with AWGN-corrupted feedback. Our outer bound is based on the idea of ...

Outer Bounds for Multiple Access Channels with Feedback using Dependence Balance
We use the idea of dependence balance to obtain a new outer bound for the capacity region of the discrete memoryless multiple-access channel with noiseless feedback (MAC-FB). We co...

Effects of cooperation on the secrecy of multiple access channels with generalized feedback
—We investigate the effects of user cooperation on the secrecy of multiple access channels with generalized feedback (MAC-GF). We show that cooperation can increase the achievabl...

Cooperative Relay Broadcast Channels
The capacity regions are investigated for two relay broadcast channels (RBCs), where relay links are incorporated into two-user broadcast channels to support user cooperation. In t...
