Network Topology Inference Using Higher-Order Statistical Characteristics of End-to-End Measured Delays

open access: yesIEEE Access, 2020
Network topology is important information for many network control and management applications. Network tomography infers network topology from end-to-end measured packet delays or losses, which is more feasible than internal cooperation-based methods ...

An automatic systolic peak detector of blood pressure waveforms using 4th order cumulants

open access: yesCurrent Directions in Biomedical Engineering, 2016
The arterial blood pressure (ABP) holds a lot of information about the cardiovascular system. To analyse the ABP signal, at first the pulse wave has to be detected correctly. Due to influences, e.g.

Local efficiency corrections to higher order cumulants

open access: yesPhysical Review C, 2015
In this brief note we derive and present the formulas necessary to correct measurements of cumulants for detection efficiency. In particular we consider the case where the efficiency may depend on the phase-space, such as transverse momentum, rapidity etc.

Sixth-Second Order Normalized Cumulant Blind Equalization Algorithm Based on Oversampling

open access: yesDianxin kexue, 2014
Most existing blind equalization algorithms rely on partial or complete channel identification, but the channel order estimation is always a difficult task.

Analytic theory of higher order free cumulants

open access: yes, 2021
We establish the functional relations between generating series of higher-order free cumulants and moments in higher-order free probability, solving an open problem posed fifteen years ago by Collins, Mingo, Śniady and Speicher. We propose an extension of free probability theory, which governs the all-order topological expansion in unitarily invariant ...

Central DOA Estimation Method for Exponential-Type Coherent Distributed Source Based on Fourth-Order Cumulant

open access: yesInternational Journal of Antennas and Propagation, 2020
The performance of direction-of-arrival (DOA) estimation for sparse arrays applied to the distributed source is worse than that applied to the point source model.

On higher-order moment and cumulant estimation

open access: yesJournal of Statistical Computation and Simulation, 2019
Moments and cumulants are involved in statistical analysis for a wide range of fields. A natural and popular approach to moment and cumulant estimation is based on the sample average. However, it is well known that these sample estimates usually perform poorly.
