Japanese Patent JP4409737

B2

PROBLEM TO BE SOLVED: To provide a wireless device that has the directivity in a direction of a desired wave and that attains sufficient suppression in directions of interference waves even under an environment where strong interference waves exist. SOLUTION: A first weight vector calculator 11.1 calculates a weight vector on the basis of signals resulting from signals received from antennas #1-#4 and passing through a narrow band pass filter 20 and of a signal resulting from a reference signal passing through a narrow band pass filter 22. A second reception weight vector calculator 11.2 directly receives reception signals RX1(t)- RX4(t) outputted from a synchronization circuit 30 and the reference signal from a memory 14.2. The second reception weight vector calculator 11.2 calculates the weight vector from the signal weighted by the weight vector from the first weight vector calculator 11.1 on the basis of synchronization position information from a synchronization circuit 32 detecting synchronization timing.
