Abstract
An input signal is input via an input part. A plurality of signal section candidate detecting parts having different detection algorithms detect an intended signal section candidate and a noise signal section candidate from the input signal. A signal section classifying part is notified of detection results from the respective signal section candidate detecting parts, and classifies the respective signal section candidates based on a combination of the detection results. The signal section classifying part classifies a signal section candidate, which is detected as an intended signal section candidate by all the signal section candidate detecting parts, as an intended signal section, classifies a signal section candidate, which is detected as a noise signal section candidate by all the signal section candidate detecting parts, as a stationary noise signal section, and classifies a signal section candidate, which is detected as an intended signal section candidate by any of the signal section candidate detecting parts and detected as a noise signal section candidate by either of the signal section candidate detecting parts, as a non-stationary noise signal section.
