Grouping Technique for Cooperative Spectrum Sensing in Cognitive Radios

Rizwan Akhtar, Adnan Rashdi and Abdul Ghafoor
Electrical Engineering Department, College of Signals, National University of Science & Technology, Pakistan


Abstract

Cognitive networks can potentially solve the
problems of spectrum scarcity by accommodating unlicensed
(secondary) users in under-utilized segments of the spectrum.
Spectrum sensing serves as the primary stimulus for a cognitive
radio and is vitally impor ....etc

Bottom-Up/Top-Down Image Parsing with Attribute Grammer
A Seminar Report
by
Remya M.R.
M105112
Department of Computer Science & Engineering
College of Engineering Trivandrum
2010-11

Abstract
The paper, presents an attribute graph grammar for image parsing on scenes with man-made
objects, such as buildings, hallways, kitchens, and living rooms. For this choose one class of
primitives 3D planar rectangles projected on images, and six graph grammar production rules.
Each producti ....etc

The use of cognitive radio techniques in wireless mobile networks can lead to significant capacity increase. Cognitive radios sense the radio spectrum environment and to switch dynamically to available frequency ranges. a framework for applying cognitive radio technology to mobile WiMAX is described in this article. In this framework , the base stations are
equipped with sensitive detectors which dynamically assign channels to
subscriber station depending upon the on spectrum availability. The frequency reuse is increased by Power control. T ....etc

Cognitive architecture

A cognitive architecture is a blueprint for intelligent agents. It proposes (artificial) computational processes that act like certain cognitive systems, most often, like a person, or acts intelligent under some definition. It is a superset of general agent architectures. The term architecture implies an approach that attempts to model not only behavior, but also structural properties of the modelled system.
Characterization
Common to cognitive architecture is the belief that understanding (human) cognitive processin ....etc

Introduction

With Cognitive Radio being used in a number of applications, the area of spectrum sensing has become increasingly important. As Cognitive Radio technology is being used to provide a method of using the spectrum more efficiently, spectrum sensing is key to this application.

The ability of Cognitive Radio systems to access spare sections of the radio spectrum, and to keep monitoring the spectrum to ensure that the Cognitive Radio system does not cause any undue interference relies totally on the spectrum sensing elements of the sys ....etc
