Multiantenna GLR detection of rank-one signals with known power spectral shape under spatially uncorrelated noise
Sala Álvarez, José; Vázquez Vilar, Gonzalo; López Valcarce, Roberto; Sedighi, Saeid; Taherpour, Abbas (2016-12-01)
Article
Accés obertWe establish the generalized likelihood ratio (GLR) test for a Gaussian signal of known power spectral shape and unknown rank-one spatial signature in additive white Gaussian noise with an unknown diagonal spatial ... -
On the performance of Hadamard ratio detector-based spectrum sensing for cognitive radios
Sedighi, Saeid; Taherpour, Abbas; Sala Álvarez, José; Khattab, Tamer (2015-07-15)
Article
Accés obertWe consider the problem of multiantenna spectrum sensing (SS) in cognitive radios (CRs) when the receivers are assumed to be uncalibrated across the antennas. The performance of the Hadamard Ratio Detector (HRD) is analyzed ... -
Spectrum sensing using correlated receiving multiple antennas in cognitive radios
Sedighi, Saeid; Taherpour, Abbas; Sala Álvarez, José (2013-11)
Article
Accés restringit per política de l'editorialSpectrum sensing is a key component for enabling the cognitive radio paradigm. In this paper, we propose a novel totally-blind spectrum sensing technique for cognitive radio device equipped with multiple antennas, namely ...
