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

The Cognitive Radio and the Cognitive Radio Networks have recently become one of the
most intensively studied paradigms in wireless communications. The main distinctive …

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

In this paper, we consider a communication scenario in which the primary and the cognitive
radios wish to communicate to different receivers, subject to mutual interference. In the …

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 …

The degree-of-freedom (DoF) regions are characterized for the multiple-input multiple-output
(MIMO) broadcast channel (BC), interference channels (ICs), including X and multihop ICs …

Like the conventional two-user interference channel, the cognitive interference channel
consists of two transmitters whose signals interfere at two receivers. It is assumed that there …

Written by the pioneers of Flash-OFDM, arguably the first commercially developed OFDMA-
based mobile broadband system in the world, this book teaches OFDMA from first principles …

This paper addresses user coexistence in cognitive radio systems by taking advantage of
opportunities that arise during ARQ retransmission. It is shown that if these opportunities are …

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 …
