In this paper, we introduce the three-user cognitive radio channels with asymmetric
transmitter cooperation, and derive achievable rate regions under several scenarios …

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 …

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 …

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 consider the additive white Gaussian noise (AWGN) cognitive fading interference
channel consisting of one primary and multiple secondary transmitter-receiver pairs. The …

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 …

Motivated by the uplink scenario in cellular cognitive radio, this study considers a
communication network in which a point-to-point channel with a cognitive transmitter and a …

In this work, we derive achievable rate regions for the three-user interference channels with
asymmetric transmitter cooperation and various decoding capabilities at the receivers. The …
