Detection and extraction of signals from the epoch of reionization using higher-order one-point statistics [PDF]

open access: yes, 2009
Detecting redshifted 21-cm emission from neutral hydrogen in the early Universe promises to give direct constraints on the epoch of reionization (EoR).

Symmetries, Invariants and Generating Functions: Higher-order Statistics of Biased Tracers [PDF]

open access: yes, 2017
Gravitationally collapsed objects are known to be biased tracers of an underlying density contrast. Using symmetry arguments, generalised biasing schemes have recently been developed to relate the halo density contrast $\delta_h$ with the underlying ...

An inertial range length scale in structure functions [PDF]

open access: yes, 2000
It is shown using experimental and numerical data that within the traditional inertial subrange defined by where the third order structure function is linear that the higher order structure function scaling exponents for longitudinal and transverse ...

Image restoration using HOS and the Radon transform [PDF]

open access: yes, 1993
The authors propose the use of higher-order statistics (HOS) to study the problem of image restoration. They consider images degraded by linear or zero phase blurring point spread functions (PSF) and additive Gaussian noise.

Higher Order Capacity Statistics of Diversity Receivers

open access: yesWireless Personal Communications, 2009
A statistical analysis for the channel capacity (CC) for several diversity receivers under optimal rate adaptation with constant transmit power is provided. Independent but not necessarily identically distributed Nakagami-m fading channels are considered. Specifically, the moments of the CC at the output of selection combining, maximal-ratio combining,

Underdetermined Blind Source Separation for Heart Sound Using Higher-Order Statistics and Sparse Representation

open access: yesIEEE Access, 2019
Underdetermined blind source separation (UBSS) is a hot and challenging problem in signal processing. In the traditional UBSS algorithm, the number of source signals is often assumed to be known, which is very inconvenient in practice. In addition, it is
