In this paper we consider low-rank estimation of room impulse responses (RIRs). Inspired by a physics-driven room-acoustical model, propose an estimator RIRs that promotes structure for matricization, or reshaping, the estimated RIR. This prior acts as regularizer inverse problem estimating RIR from input-output observations, preventing overfitting and improving accuracy. As directly enforcing ...

A neural network architecture, which models synapses as Finite Impulse Response (FIR) linear lters, is discussed for use in time series prediction. Analysis and methodology are detailed in the context of the Santa Fe Institute Time Series Prediction Competition. Results of the competition show that the FIR network performed remarkably well on a chaotic laser intensity time series.

In this paper, we present a parallel algorithm for edge detection based on Infinite Impulse Response filter (IIR filter). In particular, the Infinite size Symmetric Exponential Filter (ISEF) that is an optimal IIR filter and computationally efficient smoothing filter is studied. The proposed algorithm exploits efficiently all aspects of potential parallelism (spatial parallelism, temporal paral...

In recent years, underwater acoustic wireless sensor networks have been used in many areas. There have been many field trials of acoustic propagation models and statistics for shallow water conditions. However, field trials are limited environmentally and, hence, not widely accepted. Simulations of the impulse response of a shallow underwater acoustic channel allows less expensive system tests ...

In this paper, the distribution of zeros of mobile channels is investigated and the results obtained are applied to the GSM (Global System for Mobile Communications)/EDGE (Enhanced Data Rates for GSM Evolution) system. The taps of the discrete{time overall impulse response can be modeled as correlated complex Gaussian random variables, where the correlations depend on the transmit lter, the pow...

The time evolution of an oscillator coupled to infinite string with a discontinuous mass density is investigated. It shown that the equation motion leads nonlinear characteristic due frequency-dependent nature point impedance string. Then, method perturbation theory applied solve first order in parameter. Finally, response impulse obtained by means Green's function method.
