PROBLEM TO BE SOLVED: To improve communication quality by synthesizing a comma value from a reception signal vector, a final output of an array antenna, and an adaptive gain so as to update a gain vector, thereby adjusting a beam pattern in real time in a reception system, miniaturizing interference and reducing effects of noise. SOLUTION: A comma value synthesis section 11 receives a signal vector x outputted from a receiver that receives a signal through the use of array antenna for each snapshot, a final output value (y) of the array array antenna at a current snapshot, and a predetermined adaptive gainμand synthesis comma values for each snapshot and outputs. A gain vector update section 12 is input with the comma value from the synthesis section 11, a gain vector w, the adaptive gainμand the reception signal vector x and the output (y) of the array antenna for updating the gain vector w for each snapshot.
