In this survey paper, we characterize the learning problem in cognitive radios (CRs) and
state the importance of artificial intelligence in achieving real cognitive communications …

Cognitive radio technology, a revolutionary communication paradigm that can utilize the
existing wireless spectrum resources more efficiently, has been receiving a growing …

Transmit power in wireless cellular networks is a key degree of freedom in the management
of interference, energy, and connectivity. Power control in both the uplink and downlink of a …

Hierarchical dynamic spectrum access (DSA) has received the most attention in recent years
as the solution for better spectrum utilization. In this paper, on the other hand, we develop a …

This book examines signal processing techniques for cognitive radios. The book is divided
into three parts: Part I, is an introduction to cognitive radios and presents a history of the …

Due to the growth of community awareness, the popularity of green products has increased.
In addition, with increasing Internet usage, companies use the Internet as a direct channel …

Cognitive radio systems allow opportunistic secondary users (SUs) to access portions of the
spectrum that are unused by the network's licensed primary users (PUs), provided that the …

We propose a new framework of joint spectrum allocation and power control to utilize open
spectrum bands in cognitive radio networks (CRNs) by considering both interference …

The major contribution of this paper is distributed power allocation for a multi-user multi-
channel Cognitive Radio (CR) network which deploys overlay spectrum sharing by the …

In this paper, we propose the concept of centralized dynamic spectrum leasing (C-DSL), in
which multiple primary users belonging to the same primary system participate in the …
