METHOD FOR ELIMINATING THE EFFECT OF GAIN VARIATIONS OF A DISTRIBUTION AMPLIFIER AT A BASE STATION

摘要

The present invention relates to a method for measuring gain variations of a distribution amplifier (5) at a base station of a cellular system and for eliminating their effect, the base station comprising an antenna unit (3) and at least one receiver (7) for receiving signals transmitted by radio transmitters currently located in the radio coverage area of the base station. In order to determine the signal level of the received signals, the actual gain of the distribution amplifier (5) is measured; the value representing the actual gain is stored in a memory means (18); and, during the normal traffic use of the base station, the value stored in the memory means (18) is used for eliminating the effect of gain variations of the distribution amplifier. The invention further relates to a base station at which the method of the invention is applicable.
