Cognitive radios hold tremendous promise for increasing spectral efficiency in wireless
systems. This paper surveys the fundamental capacity limits and associated transmission …

Cognitive Radio Communications and Networks gives comprehensive and balanced
coverage of the principles of cognitive radio communications, cognitive networks, and …

With the development of cognitive radio technologies, dynamic spectrum access becomes a
promising approach to increase the efficiency of spectrum utilization and solve spectrum …

In recent years, the development of intelligent, adaptive wireless devices called cognitive
radios, together with the introduction of secondary spectrum licensing, has led to a new …

Inner and outer bounds are established on the capacity region of two‐sender, two‐receiver
interference channels (IC) where one transmitter knows both messages. The transmitter with …

We propose a network architecture that enables spectrum sharing between a primary TV
broadcast system and a secondary cellular broadband system. To compensate for the …

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 …

We consider linear precoding in the downlink of a multiuser multiple-input-single-output
(MISO) overlay cognitive radio (CR) network, wherein a primary base station (PBS) and a …

An achievable region, outer bounds and a capacity result are established for two-sender two-
receiver interference channels with one cognitive transmitter. Specifically, we assume that …

Under utilization of radio spectrum in traditional wireless communication systems [30], along
with the increasing spectrum demand from emerging wireless applications, is driving the …
