Zusammenfassung:	PROBLEM TO BE SOLVED: To carry out communication with a plurality of communication partners by using a plurality of beams without interference with each other while adaptive control is carried out by using a common parameter in transmission and receiving. SOLUTION: In a communication system 10, two or more transceiver branches 40, 41 made up of bidirectional vector modulators 22, 23, distribution/synthesizing units 26, 27, transceiver units (TRX) 28, 29, receiving units (RX) 32, 33, and adaptive processing units 30, 31 are provided.The transceiver branches 40, 41 form individually each communication beam by using a non-common circuit unit 24 made up of a RF transmission system circuit and a RF receiving system circuit and two or more common unit antennae 12.
