INTERFERENCE WAVE SUPPRESSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an interference wave suppression device that solves a problem of difficulty in compensating mismatching of frequency characteristics between channels over a full band (-0.5fs1 to 0.5fs1 ) in a weight summing means 11 in a conventional interference wave suppression device. SOLUTION: Selecting a sampling frequency of a digital quadrature/in-phase signal in the output of a phase detector 4-n higher than the sampling frequency of a signal in the weight summing means 11 can select a compensation band of a compensation filter for compensating mismatching of the frequency characteristics between channels to be nearly equal to the sampling frequency of the signal in the weight summing means 11.
