Abstract

In this paper, we derive the fast and exact implementation of multichannel filtered-S LMS (FSLMS) algorithm. By removing redundancy in the governing equations of the standard FSLMS algorithm, we can obtain a significant reduction in the complexity of the controller. This has been achieved by rearranging the equations of FSLMS algorithm. We have carried out a detailed computational complexity analysis. Simulation experiments have been carried out to show the performance equivalence of the proposed fast algorithm with its standard version.
