摘要：

The control of acoustical echoes is an important function in speech processing systems. This report discusses the application of high-order adaptive filters to the problem of acoustical echo cancellation. Means to achieve robust performance are detailed. Further, methods are presented for reducing computational complexity that allow implementations in low-cost, fixed-point digital signal processors.
