Asilomar Conference on Signals, Systems & Computers
作者: Chunjian Li S.V. Andersen Department of Communication Technology University of Aalborg Aalborg Denmark
In this paper, speech enhancement via Kalman filtering is considered. A non-stationary signal model for the speech signal is first described. This model consists of a slowly varying AR model and an excitation source t... 详细信息
