Frame domain signal processing: Framework and applications
Besides basis expansions, frames representations play a key role in signal processing. We thus consider the problem of frame domain signal processing, which is more complex and ch...

Adaptive Segmentation and Separation of Determined Convolutive Mixtures under Dynamic Conditions
Abstract. In this paper, we propose a method for blind source separation (BSS) of convolutive audio recordings with short blocks of stationary sources, i.e. dynamically changing so...

Local feedback passivation of nonlinear discrete-time systems through the speed-gradient algorithm
This paper proposes a method in order to render passive discrete-time nonlinear multiple-input multiple-output (MIMO) systems which are affine in control. The methodology is base...
