On the Nearest Singular Matrix Pencil [PDF]
SIAM Journal on Matrix Analysis and Applications, 2017 Summary: Given a regular matrix pencil \(A + \mu E\), we consider the problem of determining the nearest singular matrix pencil with respect to the Frobenius norm. We present new approaches based on the solution of matrix differential equations for determining the nearest singular pencil \(A + \Delta A +\mu( E + \Delta E)\): one approach for general ...

Matrix pencil and system poles [PDF]
Signal Processing, 1990 Abstract Poles of a linear time-invariant system can be extracted from a matrix pencil constructed from the transient response of the system. Three subspace filtering techniques applicable to the matrix pencil method are presented briefly in a unified way.

Blind Multiuser Detection for Long-Code CDMA Systems with Transmission-Induced Cyclostationarity
EURASIP Journal on Wireless Communications and Networking, 2005 We consider blind channel identification and signal separation in long-code CDMA systems. First, by modeling the received signals as cyclostationary processes with modulation-induced cyclostationarity, long-code CDMA system is characterized using a time-

Improved matrix pencil methods [PDF]
Conference Record of Thirty-Second Asilomar Conference on Signals, Systems and Computers (Cat. No.98CH36284), 2002 We study the problem of estimating signal parameters from a noisy data sequence containing superimposed damped sinusoids. We propose three novel methods by combining the reduced-rank Hankel approximation and the matrix pencil method. We demonstrate that two of the proposed methods significantly outperform both the original matrix pencil method and the ...

Application of the Non-Hermitian Singular Spectrum Analysis to the Exponential Retrieval Problem
Известия высших учебных заведений России: Радиоэлектроника, 2020 Introduction. In practical signal processing and its many applications, researchers and engineers try to find a number of harmonics and their frequencies in a time signal contaminated by noise. In this manuscript we propose a new approach to this problem.
