摘要： The filtered-X least mean-square (FxLMS) algorithm is widely used for active noise control (ANC). A long tap-length is usually required for some FxLMS applications, and consequentially the convergence rate becomes very slow. In this letter, a new variable tap-length and step-size FxLMS algorithm is proposed, especially suited to a long tap-length filter. Taking into account the lowpass filter effect in the secondary path of ANC, the new algorithm is developed for the control filter with an unsymmetric and two-sided exponential decay envelop over its impulse response. Simulation results show that the new algorithm provides faster convergence and cancellation performance compared to previously proposed variable-step-size FxLMS algorithms. 其他題名： LSP 出版者： IEEE 出版日期： 2013-11-01 出處： IEEE signal processing letters, 2013-11, Vol.20 (11), p.1122-1125 資源來源： IEEE Electronic Library (IEL) 識別號： ISSN: 1070-9908 識別號： EISSN: 1558-2361 識別號： DOI: 10.1109/LSP.2013.2282396 識別號： CODEN: ISPLEM
