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...

Self-Adaptation in Evolving Systems
A theoretical and experimental analysis is made of the effects of self-adaptation in a simple evolving system. Specifically, we consider the effects of coding the mutation and ...

An elementary result in the stability theory of time-invariant nonlinear discrete dynamical systems
The stability of the equilibria of time-invariant nonlinear dynamical systems with discrete time scale is investigated. We present an elementary proof showing that in the case of ...

On the Composition of Secure Systems
When complex systems are constructed from simpler components it is important to know how properties of the components behave under composition. In this article, we present various...

A New SLNR-based Linear Precoding for Downlink Multi-User Multi-Stream MIMO Systems
—Signal-to-leakage-and-noise ratio (SLNR) is a promising criterion for linear precoder design in multi-user (MU) multiple-input multiple-output (MIMO) systems. It decouples the p...
