Linear Time - Varying Systems

The notion of properness, well-known for constant linear systems, is generalized to the time-varying case. In a module theoretic framework intrinsic characterizations of input-output system properness are derived. For this, ltrations and the associated Hilbert polyno-mials are used. Classical criteria for properness of polynomial and state representations for constant linear systems are general...

Linear Time Varying Precoder

Linear Time Varying Precoder Applied to an ISI Channel Nader Sheikholeslami and Peter Kabal Department of Electrical Engineering McGill University, Montreal, Quebec, Canada [email protected] [email protected] Abstract A linear time varying precoding structure for data transmission over ISI channels is investigated. This precoding scheme is capable of stabilizing the inverse channel lter witho...

On the Approximation of Pseudo Linear Systems by Linear Time Varying Systems (RESEARCH NOTE)

This paper presents a modified method for approximating nonlinear systems by a sequence of linear time varying systems. The convergence proof is outlined and the potential of this methodology is discussed. Simulation results are used to show the effectiveness of the proposed method.

Linear Time-varying Darlington Synthesis

Given a contractive linear system T which is represented as a causal linear operator on a Hilbert space H. We study the question: when does there exist an isometric or unitary causal extension of T to H⊕H?
