Abstract :
A new variable-step-size (VSS) LMS algorithm is proposed and its performance is investigated through simulations. The results obtained show that superior performance can be achieved relative to that of an existing VSS algorithm. The proposed algorithm and a corresponding fixed-step-size (FSS) LMS algorithm are then applied to subband adaptive echo cancellation
