A method for the recognition of one or more useful signals within a source signal

摘要

A method for the recognition of one or more, for the transmission of useful signals or used for the discovery of potentially relevant useful signals within a broadband source signal, wherein the– a time segment of the source signal by spectral transformation is converted into a spectral signal,– from the spectral signal a frequency range is selected and by selection of a real portion of the values of the spectral signal is formed a corresponding sub-band signal,– from the sub-band signal is formed a transformed sub-band signal,– by means of multiplication of the components of the sub-band signal and of the transformed sub-band signal is formed a product signal,– the product signal with a reversal of - spectral transformation into a time signal is transformed,– from the inverse transform time signal is obtained an auto correlation pattern,– the auto correlation pattern with an amount of known auto correlation pattern is compared, wherein for each known pattern is a similarity value is calculated, wherein the auto correlation pattern vectors of numbers are of equal length and the similarity values by scalar products of such vectors can be determined, or wherein the similarity values by comparison..
