Abstract
A frame generatorframes an input signal and generates a frame signal. A reference signal storage unitstores therein a reference signal showing a periodic noise signal. A correlation value calculatorcalculates a correlation value between the frame signal and the reference signal. A correlation candidate position deciderdecides a plurality of correlation candidate positions serving as candidates for a signal portion of the reference signal correlated with the frame signal. A noise reduction processorreduces a periodic noise signal, which is included in the frame signal, by using each signal portion of the plurality of correlation candidate positions, and generates a plurality of candidate output signals. An output signal deciderdecides a candidate output signal, in which the periodic noise signal is reduced the most among the plurality of candidate output signals, and outputs the decided output signal.
