In this paper, Haar wavelet based identification of a continuous-time linear time-varying (LTV) system is proposed. For that purpose, input and output data are analyzed to derive an algebraic equation, leading to estimation of Haar wavelet coefficients for the impulse response. Finally, it is demonstrated that an LTV system can be effectively identified by solving the algebraic equation and by ...

Databases of head related impulse responses (HRIRs) for binaural synthesis can be measured either in anechoic or reflective environments. The time until energy decays to negligible values after impulsive excitation ranges from some milliseconds under anechoic conditions to some seconds in reflective environments. The computational load for dynamic binaural synthesis increases significantly with...

Many methods are available for digital computation of the impulse response from indicator-dilution measurements representing input and output signals. In all instances, the only criterion for validity of the computation is comparison of the reconvolution of the computed impulse response and the input with the actual output. In this paper, a model mathematical system was constructed with a known...
