<p>An adaptive array radio device (1010) includes A/D converters (1200.1 to 1200.n) for receiving signals from an array antenna and converting them from analog signals to digital signals, down sampling devices (1210.1 to 1210.n) for receiving outputs from the A/D converters (1200.1 to 1200.n) and performing down sampling, and an adaptive array processor (1250) for receiving an output from a synchronous position estimation device (1230) and performing adaptive array processing. According to a timing adjustment signal supplied for the down sampling devices (1210.1 to 1210.n), the adaptive array processor outputs a minimum square error signal. Thus, it is possible to accurately perform calibration of the transmission directivity of the adaptive array radio device.</p> |
