Abstract
In a radio-telephone system based on time-division multiple access, the AGC function of the receiver can be controlled so as to be approximating the actual value at the beginning of the reception timeslot. The field strength of a specific signal transmitted by a base station during a timeslot preceding a concerned reception timeslot is measured, the specific signal having a power the ratio of which to the power of the concerned signal is presumed. On the basis of this measured field strength and the presumed ratio, the required AGC gain of the AGC amplifiers is calculated and the AGC gain is set according to the calculated gain for the time of the concerned reception timeslot.
