Abstract
This method comprises steps of: a) partitioning () the spectrum of the noisy signal into a HF part and a LF part; b) operating denoising processes in a differentiated manner for each of the two parts of the spectrum with, for the HF part, a denoising by prediction of the useful signal from one sensor to the other between sensors of a first sub-array (R), by means of a first adaptive algorithm estimator (), and, for the LF part, a denoising by prediction of the noise from one sensor to the other between sensors of a second sub-array (R), by means of a second adaptive algorithm estimator (); c) reconstructing the spectrum by combining together () the signals delivered after denoising of the two parts of the spectrum, respectively; and d) selectively reducing the noise () by an Optimized Modified Log-Spectral Amplitude gain, OM-LSA, process.
