Wireless communication system, weight control apparatus, and weight vector generation method

摘要

Signals received by a plurality of antenna elements are supplied to a beam forming circuit via a distributor. The beam forming circuit weights and combines the signals to output a reception signal corresponding to a beam having a predetermined directionality pattern. A weight used to control weighting and combining is set by a weight controller. Upon receiving a registration request from an unregistered terminal, the weight controller calculates a weight vector used to form a beam having null directionality toward that terminal, and maximum directionality toward the range of an area other than an area where the terminal is located of a plurality of areas obtained by dividing the area covered by the antenna elements in accordance with direction.
