An identification technique for the co-frequency mixed communication signals based on cumulants

open access: yesEURASIP Journal on Advances in Signal Processing, 2018
Identification of the co-frequency interference is a common problem in wireless digital communication systems. The high-order statistics (HOS) feature based on cumulants is a widely adopted solution. However, prior knowledge of the timings and the symbol

Impact of resonance decays on critical point signals in net-proton fluctuations

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
The non-monotonic beam energy dependence of the higher cumulants of net-proton fluctuations is a widely studied signature of the conjectured presence of a critical point in the QCD phase diagram.

Photon-number moments and cumulants of Gaussian states [PDF]

open access: yesQuantum
We develop closed-form expressions for the moments and cumulants of Gaussian states when measured in the photon-number basis. We express the photon-number moments of a Gaussian state in terms of the loop Hafnian, a function that when applied to a $(0,1)$-

An Accurate Approximation to the Distribution of a Linear Combination of Non-Central Chi-Square Random Variables

open access: yesRevstat Statistical Journal, 2013
This paper provides an accessible methodology for approximating the distribution of a general linear combination of non-central chi-square random variables. Attention is focused on the main application of the results, namely the distribution of positive

Transport model study of conserved charge fluctuations and QCD phase transition in heavy-ion collisions

open access: yesHe jishu, 2023
The RHIC-STAR (Relativistic Heavy Ion Collider-Solenoid Tracker at RHIC) experiments have measured the cumulants of net-proton (a proxy for net-baryon), net-charge, and net-kaon (proxy of net-strangeness) multiplicity distributions in Au+Au collisions at

Unbiased Estimates for Products of Moments and Cumulants for Finite Populations

open access: yesMathematics, 2023
Let FN be the distribution function of a finite real population of size N. Let Fn be the empirical distribution function of a sample of size n drawn from the population without replacement.

Mitigating Large Background in Jet Substructure Observables [PDF]

open access: yesEPJ Web of Conferences, 2020
We discuss a new approach for jet physics analysis by using subtraction between cumulants of jet substructure observables. The subtracted cumulants are insensitive to soft-particle background uncorrelated with the hard process and allow comparisons ...

Underground signal recognition method based on higher-order cumulants and DNN model

open access: yesGong-kuang zidonghua, 2020
In view of complex and heterogeneous wireless environment of mine, an underground signal recognition method based on higher-order cumulants and DNN model was proposed to realize automatic modulation recognition of underground digital signals of BPSK ...
