  Abstract

Frequency domain adaptive filter is effective to communication fields of many computational requirements. In this paper, we propose a new variable step size algorithm, EVSS-FLMS
(Exponential Variable Step Size FLMS), which varies adaptive constant by the change of signal environment. The proposed algorithm has advantages reducing computational complexity, improving convergence speed of frequency-domain adaptive filter and this algorithm converges stably in a sudden change of system environment.
The proposed algorithm did computer simulation using adaptive noise canceler(ANC) applying synthesis speech. Analyses of convergence properties and computational complexity show that the proposed algorithm is more efficient than normalized-FLMS.
