Blind estimation using higher-order cumulants

Proceedings of ISCAS'95 - International Symposium on Circuits and Systems, 2002
This paper presents a higher-order cumulant based blind estimation algorithm for estimating the channel matrix in a n-sensor-m-source system under a noisy environment. The output from an array of n spatially separated sensors is the only available information that can be used to derive the channel parameters. The algorithm requires neither the additive

Non-gaussian ARMA identification via higher order cumulant

Signal Processing, 1993
Abstract Combining the conceptual breakthrough of minimum entropy deconvolution (MED) with higher order statistics (HOS), we present an extension algorithm of a two-step procedure to identify nonminimum phase system (NMPS). The fourth order cumulants of the observed data, rather than the innovation sequence, are used to resolve the true zero location

Higher-Order Correlations and Cumulants

2010
Recent advances in electrophysiological and imaging techniques have highlighted the need for correlation measures that go beyond simple pairwise analyses. In this chapter, we discuss cumulant correlations as natural and intuitive higher-order generalizations of the covariance.

Supplementary Appendix To: Higher-Order Multi-Cumulant Factor Analysis

SSRN Electronic Journal, 2021
In this supplementary appendix to the paper Lu et al. (2021) "Higher-order Multi- cumulant Factor Analysis", we provide a brief R tutorial for the proposed HFA method. The proposed HFA estimators are available in the open source software R in the package hofa.
