RADIO BASE STATION APPARATUS, ADAPTIVE ARRAY PROCESSING CONTROL METHOD AND ADAPTIVE ARRAY PROCESSING CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a radio base station apparatus, an adaptive array processing control method and an adaptive array processing control program which can properly extract a desired wave by adaptive array processing even if the level of the desired wave is smaller than the level of an interference wave.;SOLUTION: A transmission timing control unit 11 controls the transmission timing of a signal to a desired terminal so that the reception timing of a signal from the desired terminal may be deviated from the reception timing of an interference wave by a predetermined time or more. An adaptive array processor 10 for reception applies adaptive array processing to signals received from a plurality of antennas 1a-1d to extract a signal from the desired terminal. A reception timing control unit 8 performs control so that the adaptive array processing may be performed at a timing deviated from the reception timing of the interference wave by the predetermined time or more.;COPYRIGHT: (C)2005,JPO&NCIPI
