A method for determining and selecting transmission paths of the received signal in a mobile communication terminal, wherein - the transmission paths of the received signal and the associated path delay times and path weights are determined, and for this purpose - correlations between the transmitter side acted upon by pilot symbols received signal and the pilot symbols containing correlation signal are performed so that a delay profile is obtained averages are carried out in each case via a plurality of thus obtained delay profiles, and analysis of a respective plurality of averaged delay profiles are performed with the purpose of path selection, in which - the relevant for the correlations and the averages and the analysis parameter and the repetition interval RI these calculations as a function of the relative velocity between transmitter and receiver, the frequency deviation between the carrier frequency of the received signal and the receiving-set reference frequency and the noise level of the received signal can be adjusted.
