Claim Text:
1. A method for detecting at least two transmitted signals contained in a received signal within a same frequency channel with respectively different frequency displacements, comprising: determining a modified received signal by using nonlinear signal processing of the received signal; determining a spectrum of the modified received signal by using a Fourier transform; and detecting at least two transmitted signals contained in the received signal if at least two first spectral lines each associated with carrier signals are distinguishable within the determined spectrum from spectral components associated with noise signals and payload signals, wherein the at least two transmitted signals contained in the received signal are detected if the at least two first spectral lines of carrier signals contained in the modified received signal are identified within the determined spectrum, of which amplitudes are respectively a multiple of the mean value of an amplitude of the spectral components of the noise signals and payload signals contained in the modified received signal.
