Spectrum Sensor Employing Continuous Pilot Tones in Cognitive Radio Systems
IEEE Access, 2017 Despite the promising role of orthogonal frequency-division multiplexing (OFDM) in communication systems, the optimal and practical spectrum sensing of OFDM signals for cognitive radio systems over multipath fading channels remains an important and ...

Detection of a signal in linear subspace with bounded mismatch [PDF]
, 2006 We consider the problem of detecting a signal of interest in a background of noise with unknown covariance matrix, taking into account a possible mismatch between the actual steering vector and the presumed one.

GLRT-Based Direction Detectors in Homogeneous Noise and Subspace Interference [PDF]
, 2007 In this paper, we derive and assess decision schemes to discriminate, resorting to an array of sensors, between the H0 hypothesis that data under test contain disturbance only (i.e., noise plus interference) and the H1 hypothesis that they also contain ...

A Fast Blind Detection Algorithm for Outdoor Visible Light Communications
IEEE Photonics Journal, 2015 In this paper, we consider an outdoor visible light communication system, in which on-off keying (OOK) modulation is utilized through an atmospheric turbulence-induced slow-fading channel. A new fast blind detection algorithm is proposed by following the
