PSD estimation in beamspace using property of M-matrix
2016 IEEE International Workshop on Acoustic Signal Enhancement (IWAENC), 2016Microphone array Wiener filtering has been studied for practical sound source enhancement in noisy environments. In our previous work, the power spectral density (PSD)-estimation-in-beamspace method was proposed for estimating PSDs of target sources and surrounding noises. Assuming that source signals are uncorrelated with each other, the relationships

As mentioned in the previous chapter, modern finite difference schemes must (i) be at least of second order of approximation in all independent variables; (ii) be unconditionally stable; (iii) preserve nonnegativity of the solution. To achieve these goals, it became a common practice to involve a special apparatus of matrix theory that operates with so-

On a quadratic matrix equation associated with an M-matrix
IMA Journal of Numerical Analysis, 2003The main purpose of this work is to study the quadratic matrix equation \( X^{2}-EX-F=0\) where \(E,F,X\in \mathbb{R}^{n\times n}\), \(E\) is diagonal and \(F\) is an \( M\)-matrix. The main approach that the authors are using for solving the above quadratic matrix equation, is by transforming it into an equation that belongs to a special class of non ...

Block ILU Preconditioners for a Nonsymmetric Block-Tridiagonal M-Matrix
BIT Numerical Mathematics, 2000The paper is directed to preconditioning linear equations that arise from finite difference methods or finite elements. It is assumed that the matrix elements outside of the diagonal blocks are not positive. The assumption holds for finite difference methods and for some finite element methods of lowest order. Comparison theorems for \(M\)-matrices can
