Patent ID: 7203640

Claim:
A signal processing system comprising: an input part for inputting an input signal; a plurality of signal section candidate detecting parts for detecting an intended signal section candidate that is a candidate in a signal section in which an intended signal to be detected is recorded and a noise signal section candidate other than the intended signal section candidate from the input signal, the respective signal section candidate detecting parts using different detection algorithms for an intended signal section candidate and a noise signal section candidate; and a signal section classifying part for being notified of detection results of the respective signal section candidates from the plurality of signal section candidate detecting parts and classifying the signal section candidates based on a combination of the detection results, wherein the signal section classifying part classifies a signal section candidate, which is detected as an intended signal section candidate by all the plurality of 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 plurality of signal section candidate detecting parts, as a type-I noise signal section, and classifies a signal section candidate, which is detected as an intended signal section candidate by any of the plurality of signal section candidate detecting parts and detected as a noise signal section candidate by any of the plurality of signal section candidate detecting parts, as a type-II noise signal section.
