Abstract:
A device for detecting a useful signal by detecting a periodic signal contained in the useful signal exhibits a correlation unit for correlating the signal with the sign of the signal, taking into consideration a time delay. It also comprises an amplitude estimating unit for estimating the amplitude of the signal and a decision unit which is connected downstream of the amplitude estimating unit and the correlation unit, for deciding about the presence of the periodic signal.
