A method to eliminate interference occupying at least one part of the spectrum of one or more signals received by a network of N sensors comprises at least the following steps: subdividing each sample xi of signals into K frequency bands, weighting the samples xik obtained by subdivision, combining the different weighted coefficients Wik.Xik by given frequency band index k in order to obtain signals Sk corresponding to <math-cwu id="MATH-US-00001"> <number>1</number> <math> <mrow> <mrow> <munderover> <mo>∑</mo> <mrow> <mi>i</mi> <mo>=</mo> <mn>1</mn> </mrow> <mi>N</mi> </munderover> <mo>⁢</mo> <mstyle> <mtext> </mtext> </mstyle> <mo>⁢</mo> <mrow> <msub> <mi>w</mi> <mi>ik</mi> </msub> <mo>·</mo> <msub> <mi>x</mi> <mi>ik</mi> </msub> </mrow> </mrow> <mo>,</mo> </mrow> </math> <mathematica-file id="MATHEMATICA-00001" file="US20020122473A1-20020905-M00001.NB"/> <image id="EMI-M00001" wi="216.027" he="24.97635" file="US20020122473A1-20020905-M00001.TIF" imf="TIFF" ti="MF"/> </math-cwu> and then carrying out the combination of the signals sk for the totality of the bands K.
