During receiving of message signals, in particular radio signals, it is
particularly important to free the receiving signal of interference, such
as, e.g. noise or various kinds of interference. It would be desirable if
the receiver had knowledge of the type of occurring interference in
advance, before processing the received signal, in order therefore to be
able to improve considerably signal processing, in particular
equalisation and demodulation, of the receiving signal. A receiving
method is here proposed, in which first the auto-correlation function of
the spurious components contained in the received signal is estimated.
Then the estimated auto-correlation function is compared with presettable
sample functions and the sample auto-correlation function which most
closely corresponds to the estimated auto-correlation function is chosen.
Finally, by means of the selected sample function, further signal
processing, in particular equalisation, of the received message signal is
carried out. Therefore a matching sample function is determined in
advance for the most strongly occurring spurious component.
