Abstract
Adaptive discrete-time filters, as used, for example, in echo cancellers responsive to input signals, more specifically speech signals, which can be modelled with an autoregressive process of the order of p, a control circuit for controlling the coefficients for adjusting a discrete-time transversal filter in accordance with an algorithm which requires the same amount of computation as the Least Mean Square (LMS) algorithm but leads to the same or better convergence results for this type of signals than the Orthogonal Projection (OP) algorithm.
