Plataforma para Simulação de Sensoriamento Espectral Cooperativo em Rádios Cognitivos

This paper presents a Matlab-based simulation platform for assessing the performance of cooperative spectrum sensing in cognitive radio (CR) applications. The platform is flexible, allowing for the simulation of several sensing techniques, under a broad range of system parameters. It can be configured to consider a conventional model in which no signal processing is performed by each cooperating CR, or to consider a more realistic approach in which CR signal processing tasks are taken into account. It can also simulate a scenario with impulsive noise corrupting the received samples in each CR.
