Abstract
A method which significantly reduces a frequency offset in a base-station receiver, with the minimum effort possible, sets a reference frequency of a demodulator in each subscriber station in such a way, that its output signal no longer has a carrier frequency portion. A reference frequency for a modulator is calculated and set using the reference frequency, set in the above manner for the demodulator of the relevant subscriber station, and using all the given predetermined converter reference frequencies in the subscriber station and in the base station, on condition that a carrier frequency which occurs in the output signal of the base-station demodulator is set to zero.
