Claim:
1. A method for identifying interfering transmitters from among a plurality of known satellite transmitters, wherein a signal is determined for each satellite transmitter present via equidistant sampling of each respective signal strength and a comparison parameter for each satellite transmitter is determined for said signal, the method comprising: a) subdividing the signal into a number of succeeding signal periods of predefined equal length; b) mapping each sample value via a constant and monotonically increasing or decreasing normalization function to a normalized sample value within a predefined normal interval; c) producing a sampling vector having first and second sampling elements for each normalized sample value, a first element of said sampling vector corresponding to the normalized sample value and a second element of said sampling vector being selected such that a vector norm applied to the sampling vector yields a value of 1; d) entering the first and second sampling elements of the sampling vectors into a signal matrix, elements originating from the same signal period each being entered in the same row of the signal matrix; e) arranging first and second sampling elements of sampling vectors which were each determined at a specific sampling time instant in relation to sample values determined at a start of a respective signal period in the same column of the signal matrix, separate columns being provided for each of the first and second sampling element; f) normalizing elements of the signal matrix such that an application of a predefined vector norm to the signal matrix always yields the value of 1, or g) performing a singular value decomposition of the signal matrix into a product representation in accordance with the following relationship: where U and V h) selecting at least one row of a unitary matrix V
