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)
Open AccessWe 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 ...
Multiantenna GLR detection of rank-one signals with known power spectrum in white noise with unknown spatial correlation Sala Álvarez, José; Vázquez Vilar, Gonzalo; López Valcarce, Roberto (2012-06)
Restricted access - publisher's policyMultiple-antenna detection of a Gaussian signal with spatial rank one in temporally white Gaussian noise with arbitrary and unknown spatial covariance is considered. This is motivated by spectrum sensing problems in the ...

Restricted access - publisher's policyDynamic Spectrum Access (DSA) is receiving considerable interest as a means to improve spectral usage in licensed bands. In order to avoid interference to licensed users, spectrum sensing has emerged as an enabling technology ...
López Valcarce, Roberto; Vázquez Vilar, Gonzalo; Sala Álvarez, José (2010)
Open AccessSpectrum sensing is a key ingredient of the dynamic spectrum access paradigm, but it needs powerful detectors operating at SNRs well below the decodability levels of primary signals. Noise uncertainty poses a significant ...
