Abstract
The invention relates to a method for automatically adjusting a multiple-input-port and multiple-output-port tuning unit, for instance a multiple-input-port and multiple-output-port tuning unit coupled to the antennas of a radio transceiver using a plurality of antennas simultaneously. An automatic tuning system using this method has 4 user ports and 4 target ports, and comprises: 4 sensing units; a signal processing unit, the signal processing unit estimating real quantities depending on an impedance matrix seen by the target ports, using sensing unit output signals, 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 each of the adjustable impedance devices being mainly determined by one or more of the tuning control signals.
