An identification technique for the co-frequency mixed communication signals based on cumulants
EURASIP 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
European 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]
QuantumWe 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 $(0,1)$-

LLT cumulants and graph coloring
, 2022 The purpose of this note is to introduce a new family of quasi-symmetric functions called LLT cumulants and discuss its properties. We define LLT cumulants using the algebraic framework for conditional cumulants and we prove that the Macdonald cumulant ...

Complex Signal Constellations in Cumulants-Based AMC: Statistics and Performance
Telfor Journal, 2021 In this paper various complex signal constellations are considered in the context of Automatic Modulation Classification (AMC) based on a higher-order normalized cumulants value.

He 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
Mathematics, 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]
EPJ 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 ...
