    Abstract: The invention relates to a frequency and time synchronization of a receiver (E) for receiving OFDM signals on a fixed carrier frequency. The inventive method is characterized by determining in a first step the approximate nominal value of the frequency and of the time origin of the OFDM signal via a two-dimensional frequency-time search mode and the determination of the area point with the optimum quality criterion of the OFDM signal or via the evaluation of a synchronization sequence transmitted by the transmitter. In a subsequent second step the phase of at least one of the pilot signals transmitted together with the OFDM signal is determined in the receiver (E) and is averaged across several OFDM signal blocks; and a more exact nominal value of the frequency and of the time origin of the OFDM signal is determined therefrom. The receiver (E) is then synchronized to the frequency so determined and the OFDM signal is demodulated with the time origin value so determined.
