This paper provides a survey of the state-of-the-art information theoretic analysis for overlay
multi-user (more than two pairs) cognitive networks and reports new capacity results. In an …

Achievable rate regions and outer bounds are derived for three-user interference channels
where the transmitters cooperate in a unidirectional manner via a noncausal message …

This paper considers the K-user cognitive interference channel with one primary and K-1
secondary/cognitive transmitters with a cumulative message sharing structure, ie, cognitive …

In this paper, we derive a lower bound on the capacity of a three-user interference channel
with one cognitive transmitter. The cognitive transmitter is assumed to have noncausal …

This study investigates the capacity region of a three-user cognitive radio network with two
primary users and one cognitive user. A three-user cognitive interference channel (C-IFC) is …

In this paper, we consider a three-user cognitive radio network with two primary users and
one cognitive radio. We concentrate on a three-user Interference Channel (IFC) where one …

This paper considers the K user cognitive interference channel with one primary and K-1
secondary/cognitive transmitters with a cumulative message sharing structure, ie cognitive …

Inspired by cognitive networks, we consider the linear deterministic three-user cognitive
interference channel with one primary and two secondary/cognitive transmitters which …

We consider three-user multiple access cognitive radio channels and obtain achievable
rates for reliable communication over these channels. A synopsis of the channel model is as …

We study the degrees of freedom of the three-user Gaussian interference channel under the
circumstance where one or more transmitters are non-causally cognitive, meaning they are …
