Resumo: The spectrum sensing technique for cognitive radio networks, called CPSC (Cooperative Power Spectrum Density Split Cancellation) was recently suggested and it has been a model for continuous studies and improvements. It has some advantages like being a robust technique against dynamic noise, and also low computational complexity. From this technique, the CF-CPSC (Circular Folding CPSC) was developed, whose performance expressively overcomes the original. In this dissertation, an analysis about CF-CPSC performance was performed, over report channel errors, making a comparison between two methods. First, sendind only samples and after sending test statistics, by cognitive radios to the center fusion. The performance was also compared and evaluated applying error correcting codes, in the way of extracting best results, always observing their impact at the report channel occupation. Another contribution was developing a novel decision fusion periodogram-based algorithm for centralized cooperative spectrum sensing. Results showed the new method is sensitive to errors, however even with error correcting codes applied, the report channel traffic is smaller, leading to the conclusion that a case-by-case analysis is necessary to define wich is the best model to every situation. Altough, the decision fusion method might be applied to cases that require low data traffic at the report channel, keeping high performance.

Possui a vantagem de ser robusta contra a incerteza na estima????o do ru??do, assim como baixa complexibilidade computacional. Derivada desta t??cnica, foi desenvolvida a t??cnica CF-CPSC (Circular Folding CPSC) cujo desempenho supera expressivamente a t??cnica original. Nesta disserta????o ?? realizado, primeiramente, um estudo sobre o desempenho do m??todo CF-CPSC sob erros no canal de controle comparando dois m??todos nos quais s??o enviadas amostras do sinal ou estat??sticas de teste pelos r??dios cognitivos para o centro de fus??o. O desempenho tamb??m ?? comparado e avaliado aplicando-se c??digo corretor de erro, de forma a extrair o melhor resultado e sempre observando o impacto na ocupa????o do canal de controle. Outra contribui????o ?? o desenvolvimento de um novo algoritmo baseado no periodograma para fus??o de decis??es em sistemas de sensoriamento espectral cooperativos e centralizados. Resultados revelam que o algoritmo proposto ?? mais suscept??vel a erros. Por??m, mesmo com c??digos corretores aplicados, o volume do tr??fego de dados no canal de controle ainda ?? consideravelmente menor, levando ?? conclus??o de que uma an??lise caso a caso ?? necess??ria para definir a melhor t??cnica a ser aplicada. Contudo, o m??todo de fus??o de decis??es pode ser empregado para aplica????es que requerem baixo volume de tr??fego no canal de controle, mantendo alto desempenho.Submitted by Tede Dspace (tede@inatel.br) on 2020-01-08T13:26:39Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Disserta????o V.Final EDUARDO MOREIRA DE ALMEIDA (1).pdf: 1392606 bytes, checksum: f3d19dec78bca7a8893a90ee82a8077d (MD5)Made available in DSpace on 2020-01-08T13:26:39Z (GMT).
