Identification of Parametric Underspread Linear Systems and Super-Resolution Radar
, 2010 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.

A New Mutated Quantum-Behaved Particle Swarm Optimizer for Digital IIR Filter Design
EURASIP Journal on Advances in Signal Processing, 2009 Adaptive infinite impulse response (IIR) filters have shown their worth in a wide range of practical applications. Because the error surface of IIR filters is multimodal in most cases, global optimization techniques are required for avoiding local minima.

Infinite non-causality in active cancellation of random noise
, 2005 Active cancellation of broadband random noise requires the detection of the incoming noise with some time advance. In an duct for example this advance must be larger than the delays in the secondary path from the control source to the error sensor.

Regressor-based adaptive infinite impulse response filtering
, 1998 Superior performance of fast recursive least squares (RLS) algorithms over the descent-type least mean square (LMS) algorithms in the adaptation of FIR systems has not been realized in the adaptation of IIR systems. This is the result of having noisy observations of the original system output resulting in significantly biased estimates of the system ...

Symbol signal-to-noise ratio loss in square-wave subcarrier downconversion [PDF]
This article presents the simulated results of the signal-to-noise ratio (SNR) loss in the process of a square-wave subcarrier down conversion. In a previous article, the SNR degradation was evaluated at the output of the down converter based on the ...
