Abstract
Transmit a desired signal from a first antenna, and an interference signal from a second antenna, and calculate a weight vector by which the interference signal can be eliminated and the desired signal can be array-received by a third antenna and a fourth antenna. While having the third antenna and the fourth antenna array-transmit signals using the weight vector calculated, fluctuate the phase amount and the amplitude amount of the signals transmitted by the fourth antenna, so as to calculate a correction value from the phase amount and the amplitude amount at the time when the signal level of the signals received by the second antenna is minimum.
