Cumulant-Based Coherent Signal Subspace Method for Bearing and Range Estimation
EURASIP Journal on Advances in Signal Processing, 2007 A new method for simultaneous range and bearing estimation for buried objects in the presence of an unknown Gaussian noise is proposed. This method uses the MUSIC algorithm with noise subspace estimated by using the slice fourth-order cumulant matrix of ...

Detecting Periodicity of a General Stationary Time Series via AR(2)‐Model Fitting
Journal of Time Series Analysis, EarlyView.ABSTRACT Estimating the periodicity of a stationary time series via fitting a second‐order stationary autoregressive (AR(2)) model has been initiated by the seminal paper of Yule (1927). We investigate properties of this procedure when applied to general stationary processes possessing a spectral density with a dominant peak at some unknown frequency ...

Models and methods for frequency assignment with cumulative interference constraints [PDF]
International Transactions in Operational Research, 2008 AbstractIn this paper, a realistic modeling of interferences for frequency assignment in hertzian telecommunication networks is presented. In contrast with traditional interference models based only on binary interference constraints involving two frequencies, this new approach considers the case of cumulative disruptions that are modeled through a ...

High-resolution harmonic retrieval using the full fourth-order cumulant
, 2010 The harmonic retrieval (HR) problem concerns the estimation of the frequencies in a sum of real or complex harmonics. Both correlation and cumulant-based approaches are used for this purpose.

Variance Ratio Tests for Panels With Cross‐Section Dependence
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT This paper develops panel variance ratio statistics to examine serial dependence in time series with cross‐sectional dependence. We derive asymptotic properties for panels where the cross‐section dimension N$$ N $$ is fixed or grows with T. Using a factor structure to explain cross‐sectional dependence, we propose a common correlation effects ...

Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT A popular approach to interactive effects panel data models is the common correlated effects (CCE) estimator of Pesaran (Estimation and inference in large heterogeneous panels with a multifactor error structure. Econometrica 74, 967–1012, 2006). The current paper proposes a modified version of this estimator that is useful in a number of cases

Research on Series Arc Fault Detection Based on Higher-Order Cumulants
IEEE Access, 2019 At present, the detection methods on series arc faults are mainly based on the current of the main circuit, which probably results in misjudgment because of the singularity of the normal working current in a nonlinear load.
