Abstract

This paper presents a hybrid Fourier-EMD Regularized Deconvolution (For-EMDRD) algorithm. When the impulse response is estimated, the Fourier shrinkage and EMD shrinkage follow the ideal deconvolution result. Simulated and experimental results show that For-EMDRD not only avoidsillposed problem in deconvolution, but also improves signal edge character and Signal-to-Noise Ratio (SNR). For-EMDRD can be applied in signal estimation of acoustic wideband pulse measurement, removing the effect of transient response of a loudspeaker, eliminating the noise effect, which makes a better separation of the incident wave and reflected wave and improving the measurement accuracy of absorption coefficient.
