Journal of Telecommunications and Information Technology, 2023 This paper describes two blind algorithms for multicarrier code division multiple access (MC-CDMA) system equalization. In order to identify, blindly, the impulse response of two practical selective frequency fading channels called broadband radio ...

Higher-order Multi-cumulant Factor Analysis
SSRN Electronic Journal, 2021 We estimate the latent factors driving the non-normal dependence in high dimensional panel data using Higher-order multi-cumulant Factor Analysis (HFA). This new approach consists of an eigenvalue ratio test to select the number of non-Gaussian factors, and uses alternating regressions to estimate both the Gaussian and non-Gaussian factors.

Effect of dephasing on the current statistics of mesoscopic devices [PDF]
, 2004 We investigate the effects of dephasing on the current statistics of mesoscopic conductors with a recently developed statistical model, focusing in particular on mesoscopic cavities and Aharonov-Bohm rings.

Volume fluctuation and multiplicity correlation in higher-order cumulants [PDF]
Physical Review C, 2019 Initial volume fluctuation (VF) arising from the participant fluctuation would be the background which should be subtracted experimentally from the measured higher-order cumulants. We study the validity of the Volume Fluctuation Correction (VFC) on higher-order net-proton cumulants by using simple toy model and UrQMD model in Au+Au collisions at \sqrt ...

Simulation-Informed Evaluation of Microvascular Parameter Mapping for Diffusion MR Imaging of Solid Tumours. [PDF]
Magn Reson MedABSTRACT Purpose We aim to inform the design of new diffusion MRI (dMRI) approaches for microvasculature quantification that enhance the biological specificity of imaging towards cancer. Methods We adopted simulation‐informed modelling of the vascular dMRI signal. We synthesised signals from 1500 synthetic vascular networks, for a variety of protocols (

Blind Identification and Equalization of MC-CDMA Systems Using Higher Order Cumulants
International Journal of Advances in Telecommunications, Electrotechnics, Signals and Systems, 2014 In this work we propose an algorithm based on fourth order cumulants for identification of the linear system (Finite- Impulse Response (FIR)) with Non Minimum Phase (NMP) excited by non-Gaussian sequences, independent identically distributed (i.i.d).
