Improved Speech Enhancement Based on Higher Order Cumulants

2013 Ninth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2013
A new speech enhancement scheme based on higher order cumulants (HOC) is proposed. Under the condition of Gaussian noise, a method for estimating the probability of speech absence in each frequency bin of each frame is devised based on HOC. Further, a kind of modified Minimum Mean Square Error (MMSE) estimator based on HOC is proposed.

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.

An approach to surface EMG decomposition based on higher-order cumulants

Computer Methods and Programs in Biomedicine, 2005
We are addressing a possible approach to the decomposition of surface electromyograms (SEMGs). It is based on higher-order cumulants implemented in a two-step procedure. Firstly, a multivariate version of the w-slice method is applied in order to extract coarse approximations of motor-unit action potentials (MUAPs) out of the measured SEMGs.

Two player statistical game with higher order cumulants

Proceedings of the 2010 American Control Conference, 2010
In statistical game, multiple players optimize the distributions of the objective functions through the cost cumulants. This paper extends the use of second, third, and fourth cumulants for stochastic Nash games. For the case of linear system with quadratic cost, the equilibrium solutions are determined.

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 cyclic cumulants for high order modulation classification

IEEE Military Communications Conference, 2003. MILCOM 2003., 2004
In this paper we investigate automatic modulation classification (AMC) using homogeneous feature-vectors based on cyclic cumulants (CCs) of fourth-, sixth- and eight-orders, respectively, for QAM, PSK and ASK signals within a pattern recognition framework.
