Time-frequency detection of slowly varying periodic signals with harmonics: Methods and performance evaluation
(2011 , Article)
We consider the problem of detecting an unknown signal from an unknown noise type. We restrict the signal type to a class of slowly varying periodic signals with harmonic components, a class which includes real signals ...
Generalized Mean Phase Coherence for asynchrony abnormality detection in multichannel newborn EEG
(2012 , Conference Paper)
Inter-hemispheric asynchrony within the multichannel recordings of newborn EEG is associated with abnormal functionality of the newborn brain. Mean Phase Coherence (MPC) as a bivariate phase synchrony measure is widely ...
High-resolution time-frequency distributions for fall detection
(
SPIE
, 2015 , Conference Paper)
In this paper, we examine the role of high-resolution time-frequency distributions (TFDs) of radar micro-Doppler signatures for fall detection. The work supports the recent and rising interest in using emerging radar ...
Time-frequency compressed spectrum sensing in cognitive radios
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
In this paper, we investigate the use of time-frequency analysis for improvement of spectrum sensing in cognitive radios and exploit compressed sensing (sampling) to reduce the extremely high sampling rate of signal in ...
On the detection and estimation of correlated signal using circular antenna arrays
(
IEEE
, 2011 , Conference Paper)
This paper presents the design and analysis of smart antenna systems used for the detection and estimation of correlated radio signals encountered in multipath environments using circular antenna arrays. The MUSIC algorithm ...
