    摘要: The invention relates to a method and an apparatus for automatic tuning of an impedance matrix, for instance the impedance matrix seen by the power amplifiers of a radio transmitter using a plurality of antennas simultaneously. The apparatus has 4 user ports and 4 target ports, and comprises: 4 sensing units; a signal processing unit which estimates real quantities depending on the impedance matrix presented by the user ports, using the sensing unit output signals obtained for 4 excitations applied to the user ports, two or more of the excitations being applied simultaneously, the signal processing unit delivering a tuning instruction; a multiple-input-port and multiple-output-port tuning unit comprising adjustable impedance devices; and a tuning control unit receiving the tuning instruction and delivering tuning control signals to the multiple-input-port and multiple-output-port tuning unit, the reactance of the adjustable impedance devices being mainly determined by the tuning control signals.
