Title:
NOISE REDUCING DEVICE AND NOISE REDUCING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/208556
Kind Code:
A1
Abstract:
According to one embodiment of the present invention, a noise reducing device is provided with a detection unit, a calculation unit, and a reducing unit. On the basis of the frequency spectra of reception signals, the detection unit detects frequency components of a plurality of noise signals included in the reception signals. On the basis of frequency components detected by the detection unit, the calculation unit calculates coefficients. Corresponding to the coefficients calculated by the calculation unit, the reducing unit reduces the n number of noise signals, i.e., at least some signals of the noise signals, from the reception signals (n is a positive number of 2 or higher).
