Abstract :
A fast Hinfin filter (FHF) has been derived for identifying time-varying systems, which is capable of determining the forgetting factor that is optimal in the sense of Hinfin optimization. In this work, the performances of the FHF is evaluated in echo cancellation using a hand-made acoustic system.
