Mitigation of Ionospheric Scintillation Effects on GNSS Signals with VMD-MFDFA [PDF]

Remote Sensing, 2019
Severe scintillations degrade the satellite signal intensity below the fade margin of satellite receivers thereby resulting in failure of communication, positioning, and navigational services. The performance of satellite receivers is obviously restricted by ionospheric scintillation effects, which may lead to signal degradation primarily due to the ...

A Modified Multifractal Detrended Fluctuation Analysis (MFDFA) Approach for Multifractal Analysis of Precipitation in Dongting Lake Basin, China [PDF]

Water (Switzerland), 2019
Multifractal detrended fluctuation analysis (MFDFA) method can examine higher-dimensional fractal and multifractal characteristics hidden in time series. However, removal of local trends in MFDFA is based on discontinuous polynomial fitting, resulting in pseudo-fluctuation errors.

Asymmetric market efficiency using the index-based asymmetric-MFDFA

Physica A: Statistical Mechanics and Its Applications, 2018
Abstract We explore the asymmetric market efficiency for various countries’ stock indices using the index-based asymmetric-MFDFA. We divide market based on its trend within certain sub-period. Then, we test whether the overall, up-, and down-trend markets are efficient via the asymmetric generalized Hurst exponent.

Comparison of MFDFA and Chhabra-Jensen Method on Multifractal and Monofractal Data

2021 13th International Conference on Measurement, 2021
Researchers of different fields attempt to characterize time series in complex systems. In this comparative study, the behaviour of two well-known complexity methods called multifractal detrended fluctuation analysis (MFDFA) and Chhabra-Jensen (CJ) method was investigated.
