Modeling and identification of nonlinear systems in the short-time fourier transform domain
Abstract--In this paper, we introduce a novel approach for improved nonlinear system identification in the short-time Fourier transform (STFT) domain. We first derive explicit repr...

Sampling from a system-theoretic viewpoint part I: concepts and tools
This paper is first in a series of papers studying a system-theoretic approach to the problem of reconstructing an analog signal from its samples. The idea, borrowed from earlier t...

Adaptive precoding for downstream crosstalk precancelation in DSL systems using sign-error feedback
The performance of many very high bit rate digital subscriber line (VDSL) systems is limited by the effects of crosstalk among the wires in a bundle. For the downstream, a precoder...

Dynamic spectrum management with the competitive market model
[1, 2] have shown for the dynamic spectrum allocation problem that a competitive market model (which sets a price for transmission power on each channel) leads to a greater social...

Performance analysis of reconstruction techniques for frequency-domain optical-coherence tomography
We address the issue of noise robustness of reconstruction techniques for frequency-domain optical-coherence tomography. We consider three reconstruction techniques: Fourier, iter...
