ESTIMATION OF A SIGNAL CORRUPTED BY ACOUS TIC PULSATIONS

When the signal is corrupted with impulsive noise the usual filtering methods become defective. This paper is dedicated to impulsive noise e limination. Thus, a new technic is proposed for useful frequencies' de tection in presence of impulsive noise. This method is based on a modi fied noise cancelling technic to detect impulsive noise. The principle is to generate automatically ''noise reference'' to obtain convenable noise estimation. The method is tested on simulated signal's transmis sion. The result confirms originality and effectiveness method.
