METHOD FOR AUTOMATICALLY ADJUSTING PASSIVE TUNABLE ANTENNAS AND RADIO TRANSMITTER-RECEIVER USING THE SAME

摘要

The invention relates to a method for automatically adjusting a plurality of tunable passive antennas of a radio transceiver which communicates in a radio network using these tunable passive antennas. The invention also relates to a radio transceiver using this method. A radio transceiver according to the invention comprises: 4 tunable passive antennas (11) (12) (13) (14), each of the tunable passive antennas being part of a multiple access antenna array (1) having 4 user access; 4 detection units (31) (32) (33) (34); 4 antenna links (21) (22) (23) (24); a radio unit (8), the radio unit receiving, from a radio network, a radio signal providing an authorization to use, for excitations for tuning, one or more data symbols, the radio unit applying 4 excitations to user access, one and only one of the excitations being applied to each user access, the radio unit delivering antenna setting instructions; and a control unit (6), which delivers one or more antenna control signals to the tunable passive antennas.
