Abstract :
Blind equalisation of a speech signal that has been passed over a linear filter can be achieved by estimating the poles of the signal and separating the stationary poles due to the filter from the time varying poles due to the speech. However, identification of the position of the stationary poles, conventionally done by pole clustering, is unreliable and slow. A new algorithm for the identification of stationary poles is presented which is more accurate and faster than clustering
