Generalised phase synchrony within multivariate signals: An emerging concept in time-frequency analysis
(2012 , Conference Paper)
This paper introduces the notion of the instantaneous frequency (IF) based generalized phase synchrony in time-frequency analysis based on the concept of cointegration. This phase synchrony is then quantified by investigating ...
Time frequency analysis of the commonalities between Bitcoin and major Cryptocurrencies: Portfolio risk management implications
(
Elsevier Inc.
, 2019 , Article)
This paper uses wavelet coherence and cross wavelet transform approaches to examine co-movement between Bitcoin and five major cryptocurrencies (Dash, Ethereum, Litecoin, Monero and Ripple) and their portfolio risk ...
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 ...
Fuzzy time-frequency defect classifier for NDT applications
(
IEEE
, 2009 , Conference Paper)
In this paper, a customized classifier is presented for the industry-practiced Nondestructive Evaluation (NDE) protocols using a Hybrid-Fuzzy Inference System (FIS) to classify the and characterize the defects commonly ...
