The capacity of the Gaussian cognitive interference channel, a variation of the classical two-
user interference channel where one of the transmitters (referred to as cognitive) has …

The cognitive interference channel is a two-user interference channel in which one
transmitter is non-causally provided with the message of the other transmitter. This channel …

Broadcasting is the simplest form of communication in which nodes disseminate the same
information simultaneously to all of their neighbors. Broadcasting has been widely used in …

The smallest network model that captures relaying in the presence of multiple
communicating pairs causing interference to each other is the interference channel with a …

The interference channel with a cognitive relay (IFC-CR) consists of the classical IFC with
two independent source-destination pairs whose communication are aided by an additional …

In this paper, Network Coding (NC) Theory is introduced to improve efficiency of the
traditional ARQ scheme for Cognitive Radio (CR) broadcast, named as NC-ARQ, in which …

The capacity region of the interference channel in which one transmitter non-causally knows
the message of the other, termed the cognitive interference channel, has remained open …

In this paper, we first present an outer bound for a general interference channel with a
cognitive relay, ie, a relay that has non-causal knowledge of both independent messages …

In this paper, we study a two-user interference channel with a causal relay, where the relay's
transmit symbol depends not only on its past received symbols, but also on its present …

In this paper, taking into account the effect of link delays, we investigate the capacity region
of the cognitive interference channel (C-IFC), where cognition can be obtained from either …
