The approximate capacity of the many-to-one and one-to-many Gaussian interference channels
Recently, Etkin, Tse, and Wang found the capacity region of the two-user Gaussian interference channel to within 1 bit/s/Hz. A natural goal is to apply this approach to the Gaussia...

On the Equivalence of Two Achievable Regions for the Broadcast Channel
—A recent inner bound on the capacity region of the two-receiver discrete memoryless broadcast channel is shown to be equivalent to the Marton-Gelfand-Pinsker region. The proof m...

A stochastic control approach to coding with feedback over degraded broadcast channels
In this paper we attempt to further demonstrate connections between information theory and control, in a networked setting. Specifically, we consider the communication problem of b...

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...

Approximate Capacity Subregions of Uniform Multihop Wireless Networks
—The capacity region of multihop wireless network is involved in many capacity optimization problems. However, the membership of the capacity region is NP-complete in general, an...

Feedback Capacity of the Gaussian Interference Channel to within 2 Bits
We characterize the capacity region to within 2 bits/s/Hz and the symmetric capacity to within 1 bit/s/Hz for the two-user Gaussian interference channel (IC) with feedback. We dev...

Comments on Broadcast Channels
—The key ideas in the theory of broadcast channels are illustrated by discussing some of the progress toward finding the capacity region. The capacity region is still unknown.
