Abstract

In this digital transmission system, a control signal is transmitted at the transmitter end, by the evaluation of which signal the frequency offset of the received signal with respect to the transmitted signal can be determined. According to the invention, the frequency correction occurs in the frequency domain, that is to say, after the FFT in the receiver, by readdressing the memory contents which contain the carrier information in accordance with absolute value and phase. <IMAGE>
