The Programming of Mel Frequency Cepstrum Coefficient (MFCC) Difference´s Characteristic Extraction of Parameters and Emulation

Characteristic extraction is one of the main progresses of identification and features of this extraction must reflect not only the nature of targets but also the differences between them, in order to help the recognition unit to make classifying recognition. In this article, we study and research the characteristics of a variety of ship radiated noise spectrum, extracting the features from the perspective of noise spectrum. We have researched the extraction methods of continuous spectrum features, line-spectrum features and one and a half dimension spectrum features. In addition, this article also extracts the Mel differential cepstrum feature coefficient of the ship radiated noise and gives the final results of the simulation experiments.
