On the identification of parametric underspread linear systems
Identification of time-varying linear systems, which introduce both time-shifts (delays) and frequency-shifts (Doppler-shifts), is a central task in many engineering applications...

Identification of Underspread Linear Systems with Application to Super-Resolution Radar
Identification of time-varying linear systems, which introduce both time-shifts (delays) and frequencyshifts (Doppler-shifts) to the input signal, is one of the central tasks in m...

Convergence acceleration of the LMS algorithm using successive data orthogonalization
We propose a new adaptive filtering algorithm whose convergence rate is very fast even for a highly correlated input signal. It is well-known that convergence rate gets worse when...

MIMO experiment design based on asymptotic model order theory
Abstract— In this paper we investigate the problem of designing an input signal for a Multi-Input Multi-Output plant to minimize a control-oriented criterion. By employing Ljung...
