Abstract
New LMS adaptive noise cancellers based on multi-band structures are derived. The novel characteristics of the method are the low speech distortion and a computational burden which is merely fifty percent higher than the Widrow´s ANC. The proposed structures are immune to crosstalk, allowing higher robustness to instability and faster convergence than the CTRANC approach
