A first receiving circuit (SR1) separates the signal from a desired terminal from the signals from adaptive array antennas (#1 to #4) on the basis of the reception weight vector calculated by a reception weight vector calculator (20.1). A re-modulating circuit (32.1) generates a first replica signal from a demodulated signal of a desired wave. A replica generating circuit (40.1) multiplies the signal from the antennas by the weight vector of an interference wave from a second receiving circuit (SR2) and generates a second replica signal corresponding to the signal from the interference terminal. A reception response vector calculator (24.1) derives an impulse response of the propagation path of the signal from the desired terminal on the basis of the first and second replica signals.
