ADAPTIVE ARRAY DEVICE, WIRELESS BASE STATION AND CELLULAR TELEPHONE

摘要

A memory (237) stores relative corrections indicative of the difference in transmission characteristic between a radio section consisting of a transmitting circuit (211) and a receiving circuit (212) and a radio section consisting of a transmitting circuit (221) and a receiving circuit (222). A correction control circuit (239) corrects a transmission signal using relative corrections for a phaser (240) and an amplifier (241). In an adaptive array device and a base station, corrections are carried out so that the same array antenna pattern may form for reception and transmission.
