ARRAY-ANTENNA WIRELESS COMMUNICATION DEVICE, AND METHOD OF GENERATING WEIGHT COEFFICIENT

摘要

A null detector (108-1 to 108-3) detects the directions of null points of directivity patterns associated with mobile stations (101-1 to 101-3) and outputs information indicating the directions of the detected null points to a communicating section (109). The communicating section (109) sends all the null information to estimating sections (110-1 to 110-3). On the basis of the null information, the estimating sections (110-1 to 110-3) estimate the directions in which exist mobile stations (101-1 to 101-3) that may cause interference, and generates reception weights.
