摘要
[Problem] To find an estimated signal from which noise has been removed using a filter process on an information signal. [Solution] Provided is a signal processing method that extracts an information signal by removing noise from a measured signal that is measured in circumstances in which the information signal and noise are mixed, wherein the method obtains a plurality of measured signals from different measurement locations, detects correlations among the plurality of measured signals, detects phase synchronicity among the plurality of measured signals, and outputs a plurality of estimated signals that are estimated to be the information signal by removing uncorrelated components with low correlation and non-phase synchronous components with low phase synchronicity from each of the plurality of measured signals.
