Abstract

Acoustic echo cancellation (AEC) is an effective approach for the control of acoustic echoes generated by hands-free terminals. A fast Newton transversal filter (FNTF) algorithm models the excitation signal as an AR(M) process, where 0&leM&leN, and achieves a complexity of 2 N+12 M. The performance of FNTF in a subband AEC structure is examined, with emphasis on the identification of long echo paths typical of teleconference applications.
