Underdetermined DOA estimation exploiting the higher‐order cumulants of harmonic steering vector with time‐modulated arrays

IET Signal Processing, 2022
Time‐modulated arrays (TMAs) have been widely studied owing to their convenient control mode and simple structure. Although direction‐of‐arrival (DOA) estimation based on TMA has garnered considerable attention, underdetermined DOA estimation in TMA is ...

Correlating Fourier phase information with real-space higher order statistics [PDF]

, 2013
We establish for the first time heuristic correlations between harmonic space phase information and higher order statistics. Using the spherical full-sky maps of the cosmic microwave background as an example we demonstrate that known phase correlations ...

Higher-order Convergence Statistics for Three-dimensional Weak Gravitational Lensing [PDF]

, 2010
Weak gravitational lensing on a cosmological scales can provide strong constraints both on the nature of dark matter and the dark energy equation of state. Most current weak lensing studies are restricted to (two-dimensional) projections, but tomographic

STATISTICAL METHODS IN AI: RARE EVENT LEARNING USING ASSOCIATIVE RULES AND HIGHER-ORDER STATISTICS [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Rare event learning has not been actively researched since lately due to the unavailability of algorithms which deal with big samples. The research addresses spatio-temporal streams from multi-resolution sensors to find actionable items from a ...

Higher-order Statistics of Weak Lensing Shear and Flexion [PDF]

, 2010
Owing to their more extensive sky coverage and tighter control on systematic errors, future deep weak lensing surveys should provide a better statistical picture of the dark matter clustering beyond the level of the power spectrum.

Adaptation to changes in higher-order stimulus statistics in the salamander retina.

PLoS ONE, 2014
Adaptation in the retina is thought to optimize the encoding of natural light signals into sequences of spikes sent to the brain. While adaptive changes in retinal processing to the variations of the mean luminance level and second-order stimulus ...

Improved resolving capabilities of linear array using 2qth order non‐circular statistics

IET Signal Processing, 2021
Resolving more sources than sensors is always of interest to researchers. For this purpose, generation of the virtual array from the non‐uniform linear array has recently gathered a lot of attention.

Recurrence relations for higher moments of order statistics from doubly truncated Burr distribution

Statistica, 2014
In this paper, we have obtained recurrence relations for higher moments of order statistics from doubly truncated Burr distribution, which enable one to obtain all the single, double (product) and higher moments of any order of all order statistics for ...
