The Capacity Region of Large Wireless Networks
The capacity region of a wireless network with n nodes is the set of all simultaneously achievable rates between all possible n2 node pairs. In this paper, we consider the questio...

Capacity Regions and Bounds for a Class of Z-interference Channels
We define a class of Z-interference channels for which we obtain a new upper bound on the capacity region. The bound exploits a technique first introduced by Korner and Marton. A ...

Compound Multiple Access Channels with Partial Cooperation
A two-user discrete memoryless compound multiple access channel with a common message and conferencing decoders is considered. The capacity region is characterized in the special ...

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...

The Gaussian MAC with Conferencing Encoders
We derive the capacity region of the Gaussian version of Willems's two-user MAC with conferencing encoders. This setting differs from the classical MAC in that, prior to each ...

On the inner and outer bounds for 2-receiver discrete memoryless broadcast channels
We study the best known general inner bound[1] and outer bound[2] for the capacity region of the two user discrete memory less channel. We prove that a seemingly stronger outer bou...

On the Sum-Capacity of Degraded Gaussian Multiaccess Relay Channels
The sum-capacity is studied for a K-user physically degraded Gaussian multiaccess relay channel (MARC). Decodeand-forward (DF) is shown to achieve the sum-capacity and capacity reg...

New Bounds for the Capacity Region of the Finite-State Multiple Access Channel
The capacity region of the Finite-State Multiple Access Channel (FS-MAC) with feedback that may be an arbitrary time-invariant function of the channel output samples is considered....

New Outer Bounds on the Capacity Region of Gaussian Interference Channels
Abstract-- An outer bound on the capacity region of the twouser Gaussian interference channel is derived. The bound shows that for low power and small crosstalk coefficients the su...

Capacity Bounds for the Gaussian Interference Channel
Abstract-- The capacity region of the two-user Gaussian Interference Channel (IC) is studied. Two classes of channels are considered: weak and mixed Gaussian IC. For the weak Gauss...
