Detection of PPM-UWB random signals
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008-04-23)
Article
Accés obertThis paper focuses on the symbol detection problem of random pulse-position modulation (PPM) ultrawideband (UWB) signals in the absence of interframe interference. Particular attention is devoted to severely time-varying ... -
Frequency-domain GLR detection of a second-order cyclostationary signal over fading channels
(2014-04-01)
Article
Accés obertCyclostationary processes exhibit a form of frequency diversity. Based on that, we show that a digital waveform with symbol period T can be asymptotically represented as a rank-1 frequency-domain vector process which ... -
Frequency-domain GLR detection of cyclostationary signals in frequency-selective channels
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés obertThe frequency diversity exhibited by cyclostationary signals is exploited in this paper. A novel rank-1 frequency-domain representation of a digital waveform is proposed to address the generalized likelihood ratio (GLR) ... -
Multi-satellite cycle-slip detection and exclusion using the noise subspace of residual dynamics
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés obertReal-time detection of cycle-slips on undifferenced carrier-phase measurements is an important task to properly exclude wrong phase trackers from precise positioning algorithms. The detection is especially challenging in ... -
Multiantenna GLR detection of rank-one signals with known power spectral shape under spatially uncorrelated noise
(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 ... -
Nonuniform sampling walls in wideband signal detection
(2014-01-01)
Article
Accés obertThis work shows the existence of sampling walls in detection of wideband signals from Bernoulli nonuniform sampling (BNS) in the presence of noise uncertainty. A sampling wall is defined as the sampling density below which ...
