The filtered-x least mean square algorithm (FxLMS) is a widely used technique in active noise control. In a conventional FxLMS algorithm, the value of convergence coefficient is kept constant which may not yield optimum performance if frequency of the primary noise changes. For some frequencies, ...

This paper presents a comprehensive overview of the frequency-domain filtered-x least mean-square (FxLMS) algorithms for active noise control (ANC). The direct use of frequency-domain adaptive filters for ANC results in two kinds of delays, i.e., delay in the signal path and delay in the ...
It uses two cross-coupled filtered-X least mean square (LMS) adaptive filters to perform noise control and on-line error-path modeling simultaneously. A lattice structure is developed to decorrelate the reference input, which improves the convergence rate of the proposed algorithm...
