Canceling Sinusoidal Interferences In Ultrasonic Applications With A Bss Algorithm For More Sources Than Sensors
Jorge Igual, Andrés Camacho, Luis Vergara · 2001
Sinusoidal interferences are found in ultrasonic signals when we try to characterize a material, as for example interferences coming from PC cards. We are interested in obtain a robust method that cancels these interferences preserving the waveform of the signal. A Blind Source Separation BSS method to extract these sinusoids is presented in this paper. We will get so many linear mixtures of the backscattering echo of the material and the sinusoids as we need from different pulse responses of the material.
