摘要
Abstract
The process on the basis of characteristic parameters and classifier is built in this thesis .Nonlinear character‐istics extracted from the chord are used in constructing classifier and experiments .Although different chords have different phase space reconstruction parameters ,the value of delay‐time and embedding dimension has to be fixed .And part of the nonlinear characteristics will be lost which lower the recognition accuracy .For making up the disadvantage mentioned above , EMD adaptive signal decomposition methods are used in preprocessing .The result of experiments show that different type of chords can be recognized by this method .关键词
