    Cognitive control is part of a wider framework called cognitive dynamic systems, which builds on a paradigm of cognition composed of five elements: perception-action cycle, memory, attention, intelligence, and language. Any closed-loop feedback control system is based on the perception-action cycle. Adaptive control systems, it can be argued, incorporate the attention and intelligence aspects of t...

    This paper is inspired by how cognitive control manifests itself in the human brain and does so in a remarkable way. It addresses the many facets involved in the control of directed information flow in a dynamic system, culminating in the notion of information gap, defined as the difference between relevant information (useful part of what is extracted from the incoming measurements) and sufficien...

    In this survey, we present a comprehensive list of major known security threats within a cognitive radio network (CRN) framework. We classify attack techniques based on the type of attacker, namely exogenous (external) attackers, intruding malicious nodes and greedy cognitive radios (CRs). We further discuss threats related to infrastructure-based CRNs as well as infrastructure-less networks. Besi... View full abstract»

    This article presents a thorough description of Doherty power amplifier design and operation. The following are also highlighted: overview of the modern trends using Doherty techniques for multistage and asymmetric multiway structure; the basic operation principle of a conventional Doherty power amplifier is analysed and described; asymmetric N-way Doherty amplifier; and the design on implementing...

    In modern wireless communication systems, it is very important to realize simultaneously high-efficiency and linear operation of power amplifiers. This paper-overview describes the historical aspect of the Doherty approach to the power-amplifier design introduced in 1936 and modern trends in Doherty amplifier (DA) design techniques using multistage and asymmetric multiway architectures. To increas... View full abstract»
