摘要：The present invention comprises: first periodicity providing means (54) foremphasizing periodicity of a fixed code vector output from at least one fixed excitation
code book by use of a first periodicity emphasis coefficient adaptively determined basedon a predetermined rule; and second periodicity providing means (58) for emphasizingperiodicity of a fixed code vector output from at least one fixed excitation code book byuse of a predetermined second periodicity emphasis coefficient.
