摘要
The method involves determining the short term spectral parameters for an audio frequency signal (S0(n)) using q successive prediction stages p where q is larger than or equal to p. Each stage performs analysis of the coefficients of order Mp=a1p...aMpp to analyse the input signal S0(n) and the signal sp(n) of a stage (p+1) using a filter transfer function: Ap(z)=1+Sumä(from i=1 to mp))aip*z(-1)ü The number of linear predictive coefficients is increased for the following stage.
