Resumo: Multiantennas cognitive radios (CRs) have been used in spectral sensing to improve detection performance, but the majority of the works do not consider correlation, due to antenna proximity, in the received signals and antenna calibration errors. Therefore, this dissertation presents both performance analyzes using two blind statistical tests, the well-known GLRT (generalized likelihood ratio test) and the CFCPSC (Circular Folding Cooperative Power Spectrum Density Split Cancellation), in CCSS (centra lized cooperative spectrum sensing) with HD (hard decision) and SD (soft decision) assuming correlated received signals due to the proximity of the antennas and dynamic noise. It is also adopted frequency-selective fading according to the WRAN (wireless regional area network) standard IEEE 802.22 to give a more practical appeal to the analyses at hand. The scenarios in CCSS adopt different numbers of secondary users (SUs) and antennas per SU. At first, the performance analysis is carried out observing only the effect of the correlation of the received signal, considering the same noise power in each antenna of each SU. Then, in order to simulate a more complete scena rio, besides the correlation, different noise power in each antenna of each SU is also applied. The results showed great advantages in favor of CFCPSC.

Esta disserta????o apresenta ambas as an ??lises do desempenho usando dois testes estat??sticos cegos, o conhecido teste de m??xima verossimilhan??a ge neralizado (generalized likelihood ratio test, GLRT) e o cancelamento por divis??o de densidade espectral de potencia cooperativo por dobradura circular (circular folding cooperative power spectral density split cancellation, CFCPSC), sob sensoriamento espectral cooperativo centralizado com hard decision (HD) e soft decision (SD), considerando correla????o nos sinais recebidos e ru??do din??mico. Tamb??m ?? admitido des- vanecimento seletivo em frequ??ncia (SF) de acordo com o padr??o IEEE 802.22 para WRAN para dar um apelo mais pr??tico as an??lises em quest??o. Os cen??rios considerados adotam diferentes quantidades de USs e antenas por US. Inicialmente a an??lise do desempenho e feita observando apenas o efeito da correla????oo do sinal recebido, considerando a mesma potencia de ru??do em cada antena de cada US. Em seguida, com o intuito de simular um cen??rio mais completo, al??m da correla????o??e tamb??m considerado diferentes pot??ncias de ru??do em cada antena de cada US. Os resultados apresentaram grandes vantagens em favor do CFCPSC.Submitted by Tede Dspace (tede@inatel.br) on 2022-02-10T20:01:58Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Disserta????o V.Final F??tima Sayury.pdf: 2174934 bytes, checksum: b6c03e5832d8283727cf19d37b6f2a9b (MD5)Made available in DSpace on 2022-02-10T20:02:51Z (GMT).
