PROBLEM TO BE SOLVED: To provide a wireless relay method whereby a correlation value itself obtained by a correlation arithmetic operation is used for the parameter of a forgetting factor to decide tracing to a target adjustment amount, and the accuracy of eliminating an interference wave is enhanced by cancelling the interference wave. SOLUTION: A DSP 19 normalizes the correlation value of a correlation signal obtained by the correlation arithmetic operation by adopting a maximum correlation value for the unity, uses the value for the forgetting factor for a weighting arithmetic operation to obtain an output signal, calculates a signal whose phase is shifted from the phase of the output signal by 180 degrees, performs an arithmetic operation of adding the calculated signal to a present interference suppression signal to obtain a succeeding interference suppression signal, adjusts an ATT 15c and a PS 15b to generate the succeeding interference suppression signal, and a directional coupler 11 couples the interference suppression signal to the received signal to cancel the interference wave.
