1. A wireless communication system which allows simultaneous communications with a plurality of terminals by space-division multiplex access, comprising:

  • a plurality of antenna elements that receive a signal transmitted from the terminals;

    a plurality of beam forming units configured to output reception signals corresponding to beams having predetermined directionality patterns by weighting and combining reception signals received by said plurality of antenna elements; and

    a controller configured to set weight vectors used to control weighting and combining in said plurality of beam forming units, wherein when said controller receives a registration request from an unregistered terminal, said controller calculates and stores at least one of said weight vectors used to form a beam having;

    null directionality toward the unregistered terminal; and

    maximum directionality toward a specific area other than an area where the unregistered terminal is located of areas obtained by dividing a cover area covered by the wireless communication system.
