Overhead Reduction in Cooperative Spectrum Sensing Via Sequential Detection in Cognitive Radio Networks Under Bandwidth Constraint

O relatório sobre um instrumento operacional de gestão de pessoas é um trabalho que consiste na análise crítica de um instrumento operacional de gestão de pessoas ou na concepção

It is based on using the channel of the licensed user (also called primary user, PU), if the PU is not using it and without harmful interference. The harmful interference is

A Fundação de Serralves foi criada em 1989 16 , assumindo como missão principal a construção, na cidade do Porto, de um Museu de Arte Contemporânea de âmbito nacional

This scheme was proposed as a solution to the problem of noise uncertainty, fading and shadowing. This scheme decreases the probabilities of false detection and false

Cognitive Radio (CR) is a developing technology to overcome the problem of using the spectrum inefficiently by improving idle spectrum utilization in both temporally and spatially.

The present study contributes to draw a sketch of the use of remote sensing in current landslide studies in Europe and shows that remote sensing can be considered a powerful

CR is an persuasive resolution to the spectral congestion crisis by establishing the opportunistic exploitation of unused frequency bands that are not significantly engaged through

By introducing the trust scheme into the fuzzy logic scheme to represent the reliability of the nodes, a cooperative spectrum sensing scheme based on trust and fuzzy logic for
