Capacity of Symmetric K-User Gaussian Very Strong Interference Channels
—This paper studies a symmetric K user Gaussian interference channel with K transmitters and K receivers. A “very strong” interference regime is derived for this channel setu...

Outer Bounds for the Interference Channel with a Cognitive Relay
In this paper, we first present an outer bound for a general interference channel with a cognitive relay, i.e., a relay that has non-causal knowledge of both independent messages t...

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...

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...
