Nonlinear ANC Using a Third-Order Volterra Filter with an LDL-FAP Algorithm
نویسندگان
چکیده
Active noise control (ANC) systems employing the conventional fast affine projection (FAP) algorithms may lead to low ANC performance when the non-unity step size is chosen. To solve the problem, an LDL T fast affine projection algorithm was proposed recently for the linear ANC. In this paper, the LDL T -FAP algorithm is further utilized, along with a third-order Volterra filter, for nonlinear ANC. Simulation results show that the proposed approach yields the good nonlinear ANC performance even in wide range of step sizes.

A Filtered-X RLS Algorithm for Nonlinear Active Noise Control
In this paper, a filtered-x recursive least squares (FX-RLS) algorithm based on adaptive 3rd-order Volterra filtering is proposed for nonlinear active noise control (ANC) of systems with a nonlinear primary acoustic path. The simulation results show that the proposed approach yields faster convergence, compared with the conventional methods (e.g., FX-NLMS and FX-GSPAP), for the nonlinear ANC. K...

Active noise control (ANC) systems have been increasingly researched and developed [1]. The use of the modified filtered-x structure for ANC using finite impulse response (FIR) adaptive filtering [2] will be assumed in the rest of this paper (Fig. 1). The multichannel versions of the filtered-x least-mean-square (FX-LMS) and the modified FX-LMS (MFX-LMS) algorithms are the benchmarks to which m...

This paper proposes a new method for online secondary path modeling in feedback active noise control (ANC) systems. In practical cases, the secondary path is usually time-varying. For these cases, online modeling of secondary path is required to ensure convergence of the system. In literature the secondary path estimation is usually performed offline, prior to online modeling, where in the prop...
متن کاملIdentification of Svd-parafac Based Third-order Volterra Models Using an Arls Algorithm
A broad class of nonlinear systems can be modeled by the Volterra series representation. However, the practical use of such a representation is often limited due to the large number of parameters associated with the Volterra filter structure. This paper is concerned with the problem of identification of third-order Volterra systems. The SVD technique is used to represent the quadratic Volterra ...
