Resumo: Maximizing the secondary cognitive radio network throughput under the restriction of avoiding interference to the primary network is a main concern in recent research. In the classic approach, a specific time interval is designed to the task of spectrum sensing, which penalizes the secondary network throughput. Aiming at a higher throughput than in the classic approach, the continuous sensing mode can be adopted. In this mode, secondary receiving nodes sense the spectrum while other secondary users simultaneously transmit in the same frequency band. In this work it is compared, under the continuous sensing approach, the performances of centralized spatiotemporally cooperative spectrum sensing techniques. Altered versions of the well-established energy detection, maximum eigenvalue detection, maximum-minimum eigenvalue detection and generalized likelihood ratio test techniques are considered. In what concerns the fusion rules, we consider the sample fusion, the decision fusion and a recently proposed eigenvalue fusion technique. It is shown that, in spite of the intrinsic interference present in the continuous mode, this approach is flexible in terms of the sensing time, eventually allowing for better sensing performance.

Na abordagem convencional, determinados intervalos de tempo s?o reservados para a tarefa de sensoriar o espectro, o que penaliza a vaz?o de dados da rede secund?ria. Objetivando transmitir um volume de dados maior que no modelo convencional, pode ser adotado o modelo de sensoriamento cont?nuo. Neste modelo, os n?s de recep??o sensoriam o espectro enquanto outros usu?rios secund?rios transmitem na mesma faixa de frequ?ncia. Neste trabalho, s?o comparados os desempenhos de t?cnicas de sensoriamento espectral centralizado com coopera??o espa?o-temporal, sob a abordagem do sensoriamento cont?nuo. S?o consideradas vers?es alteradas das conhecidas t?cnicas de detec??o por energia, detec??o por m?ximo autovalor, detec??o por m?ximo e m?nimo autovalor e teste de raz?o de verossimilhan?a generalizado s?o consideradas. Quanto aos esquemas de fus?o, s?o consideradas a fus?o de amostras, a fus?o de decis?es e um esquema de fus?o de autovalores proposto recentemente. ? mostrado que, apesar da interfer?ncia intr?nseca ao modelo de sensoriamento cont?nuo, esta abordagem ? flex?vel em termos de tempo, eventualmente permitindo um melhor desempenho do sensoriamento.Submitted by Tede Dspace (tede@inatel.br) on 2016-06-27T14:51:27Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Disserta??o V.Final Mario Henrique Pereira Alves.pdf: 2634074 bytes, checksum: 4e8c819ea841ffa72541f651674cdc53 (MD5)Made available in DSpace on 2016-06-27T14:51:27Z (GMT).
