摘要：
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. (c) 2008 Elsevier B.V. All rights reserved.
