PROBLEM TO BE SOLVED: To solve a problem in a conventional interference wave suppression device that it cannot compensate mismatching of frequency characteristics between channels regardless of employing a compensation filter for the purpose in the case that the length of signal cables 31, 31-N cannot be made equal from necessity although it is desirable. SOLUTION: When a main antenna 100 and an auxiliary antenna 1-N receive an interference wave signal, a coefficient of each compensation filter EN(z) is selected so as to minimize the sum and the difference between an output signal from a delay device 5 and an output signal from each compensation filter EN(z) and a weight of an adaptive weight 7-N is decided to minimize the power of the output signal from a subtractor 10. |
