摘要: This paper proposes a new method for active noise control systems with online secondary-path modeling. The main features of the proposed are that modified-FxLMS (MFxLMS) algorithm is used in adapting filter and variable step-size (VSS) LMS modeling filter. varied accordance power residual error signal (the desired response filter). It found corrupted by which decreasing nature, (ideally) converging to zero. Hence, small initially later its value increased accordingly. Computer simulations show gives better performance than existing methods.
