Abstract
The present invention relates to a method (300) for compensating output efficiency of a plurality of amplifiers arranged to operate with an antenna array, where the antennas in the antenna array are electromagnetically coupled to each other, for providing a desired functionality of the antenna array, the method (300) comprising the steps of obtaining (301) input signal characteristics for each amplifier; determining (302) suitable compensating control parameters for each amplifier based on at least one of the input signal characteristics of each antenna and pre-determined coupling factors between antennas; outputting (303) efficiency control signals for adjusting at least one amplifier control parameter relating to output efficiency of each antenna.
