Secondary path is the path from the output of the adaptive filter to the output of the error sensor. Figure. 1- Block diagram of FxLMS algorithm. In system identification when a secondary path follows the adaptive filter, the FxLMS algorithm is usually applied for updating the adaptive filter. Although several. Abstract—The filtered-x LMS (FxLMS) algorithm has been widely used in active FxLMS algorithm in broadband ANC systems with online secondary-path.

The proposed filter increases the computational efficiency of the algorithm, without changing its convergence behavior. Please wait for a couple of weeks.

Abstract his paper extends the existing work on the root locus analysis of FxLMS algorithm by considering secondary path modeling errors. Updated 23 Nov The theoretical results are verified in practice by busing an experimental system.
