Abstract

The invention relates to a device for calculating FSM bits by means of which the signals sent from two antennas of a base station are influenced with reference to their phase difference and/or their amplitudes. The FSM bits are calculated with the aid of two estimated channel impulse responses. The device is present in hard-wired form.
