Journal ArticleDOI
Fast communication: Fast exact multichannel FSLMS algorithm for active noise control
TL;DR: This paper derives the fast and exact implementation of multichannel filtered-S LMS (FSLMS) algorithm by removing redundancy in the governing equations of the standard FSLMS algorithm by rearranging the equations.
Journal ArticleDOI
A computationally efficient frequency-domain filtered-X LMS algorithm for virtual microphone
TL;DR: A new frequency-domain virtual FXLMS algorithm is derived by implementing all of the secondary path transfer functions in the frequency domain, citing its advantages for use as an efficient real-time active noise control algorithm.
Journal ArticleDOI
Nonlinear feedback active noise control for broadband chaotic noise
TL;DR: It is shown that the proposed nonlinear controller is capable to control the broadband chaotic noise using feedback ANC which uses only one microphone whereas the conventional filtered-X least mean square (FXLMS) algorithm is incapable for controlling this type of noise.
Journal ArticleDOI
Adjoint nonlinear active noise control algorithm for virtual microphone
TL;DR: The filtered-error based algorithm using the adjoint of the secondary path is used to develop both linear and nonlinear ANC controllers with the later based on the functional link artificial neural network.
Journal ArticleDOI
Particle swarm optimization based nonlinear active noise control under saturation nonlinearity
TL;DR: A method to overcome the saturation nonlinearity linked to the microphones and loudspeakers of active noise control (ANC) system is proposed where the particle swarm optimization (PSO) algorithm is suitably applied to tune the parameters of a filter bank based functional link artificial neural network (FLANN) structure.
