Set-Membership Fast-NLMS Algorithm for Acoustic Echo Cancellation

This communication deals with the problem of Acoustic Echo Cancellation (AEC) by reduced complexity adaptive filtering algorithms. In this context, we propose to use the Set-Membership filtering concept with the Fast Normalized Least Mean Square Algorithm (SM-FNLMS). The proposed SM-FNLMS algorithm shows a superior convergence speed performances compared with the classical Set-Membership NLMS (SM-NLMS) and NLMS algorithms.
