Abstract: A method and an arrangement for synchronizing a receiver for digital signals are described. The synchronizing information is derived from the center of distribution of the squared channel impulse response, which center of distribution is calculated directly from the sampling values of the channel frequency response. Thus a separate calculation of the channel impulse response via an inverse Fourier transform from the channel frequency response is unnecessary. The channel frequency response can be determined in a simple way by correlation of a received signal with a reference signal stored in memory in the receiver.

Abstract: A method is proposed that is used for frequency correction in multicarrier processes. A received signal is shifted by means of a predetermined frequency into the base band and then subjected to a modified Fourier transform. From the Fourier transformed signal, a measurement variable is ascertained that is proportional to the frequency deviation between the predetermined frequency and the frequency of the carrier signal. This measurement variable is taken into account in the Fourier transform and thus the frequency deviation is compensated for.
