W-CDMA/TDD BASE STATION AND ARRAY ANTENNA DIRECTIVITY CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a W-CDMA/TDD base station provided with a function of reducing the effect of an arriving strong interference wave. SOLUTION: An array algorithm control section 105 receives the outputs of a plurality of inverse spread sections 103, carries out a prescribed algorithm, and outputs a weight control signal to direct a null of an adaptive array antenna 102 to an array synthesis section 104 in the direction of an FDD terminal 703. The array synthesis section 104 receives the outputs of a plurality of the inverse spread sections 103, applies weighting to the outputs amplifier circuit according to the weight control signal from the array algorithm control section 105 and gives a desired signal from the TDD terminal 702 to a channel estimate/pass synthesis section 713.
