摘要：
A novel signal model consisting of a weighted sum of complex frequency modulated subsignals is proposed in this paper. The approach can be used for the purpose of feature-based modelling of non-stationary signals like speech. The method for estimating the parameters of the proposed model is presented in detail. The developed model is found to be well suited for parametric modelling of unvoiced speech phonemes. (C) 1997 Elsevier Science B.V.
