RADIO DEVICE, TRANSMISSION/RECEPTION DIRECTIVITY CONTROL METHOD, AND TRANSMISSION/RECEPTION DIRECTIVITY CONTROL PROGRAM

摘要

A radio device (1000) includes an array antenna (10) including a plurality of antennas (#1 - #n); an adaptive array processing unit (20) multiplying signals provided from the respective antennas of the array antenna by receive weights, and thereby extracting a signal received from desired another radio device; a switch circuit (12.1) provided corresponding to at least one of the plurality of antennas for providing the signal received from the corresponding antenna to the reception signal processing unit in a receive operation; and a transmission amplifier (50) amplifying and providing a modulated transmission signal to the first switch circuit (12.1) corresponding to the one of the plurality of antennas.
