Ofdm-oqam as spectrum sensing technique

ABSTRACT: Spectrum sensing is a key function for the dynamic spectrum access. Filter bank-based multi-carrier communication techniques have been proposed as potential candidates for the physical layer of secondary users since can be used for both data communication and spectrum sensing with no addit...

description ABSTRACT: Spectrum sensing is a key function for the dynamic spectrum access. Filter bank-based multi-carrier communication techniques have been proposed as potential candidates for the physical layer of secondary users since can be used for both data communication and spectrum sensing with no additional cost. In this paper we evaluate one of these techniques, OFDM-OQAM, from the point of view of its misdetection probability as a function of the SNR and considering the multipath effect in the channel. It is showed that OFDM-OQAM outperforms the periodogram for low SNR values.

Diversas técnicas de comunicación multiportadora basadas en bancos de filtros han sido propuestas como candidatas potenciales para la capa física de usuarios secundarios, ya que pueden ser usadas tanto para la comunicación de datos como para el sensado del espectro sin un costo adicional. En este artículo se evalúa una de estas técnicas, OFDM-OQAM, desde el punto de vista de su probabilidad de no detección como función de la relación señal a ruido y considerando el efecto multitrayectoria del canal. Se muestra que OFDM-OQAM presenta un mejor desempeño que el periodograma para valores bajos de relación señal a ruido.COL00444486application/pdfengPolitécnico Colombiano Jaime Isaza CadavidMedellín, Colombiahttp://creativecommons.org/licenses/by-nc-sa/2.5/co/https://creativecommons.org/licenses/by-nc-sa/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Ofdm-oqam as spectrum sensing techniqueOfdm-oqam como técnica de sensado del espectroArtículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionSpectrum sensingDynamic spectrum accessOFDM-OQAMFilter bankSensado del espectroBancos de filtrosAcceso dinámico al espectroRev.
