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.

A brief explanation on the system and line by line comments are provided. I was especially looking for an ordinary LMS implementation without using the MatLab functions – which you’ve done quite easily.
