  • Method and system for locating interferences by frequency sub-band
    Patent number: 8655298
    Abstract: A technique for locating sources interfering on a signal received by a receiver comprising an array of antennas calculates a spatio-temporal intercorrelation matrix Rxx, subdivides the useful band of the signals into sub-bands (b), and for each sub-band (b), calculates the spatial intercorrelation matrix R(b) associated with the sub-band (b) and calculates at least one of its eigenvalues {?1, ?2, . . . ?M}. Interference in the sub-band is detected with the aid of the following detection criterion: log ? ( ( ? m = k M ? ? m ) ? / ? ( M - k + 1 ) ) - log ? ( ? m = k M ? ? m ) ? / ? ( M - k + 1 ) > threshold , and determining the eigenvectors {U1, U2, . . .
