Abstract Following a brief discussion on basic LMS algorithms, the ELMS algorithms with steady small MSE is introduced. The new algorithm using the adaptive NLMS signal-estimator to predict the signal s(k). Forgetting factor λi and error signal are used to control the step size update for iteration. Theoretics analysi and computer simulations demonstrate that the presented algorithm has good performance both in convergence properties and steady small misadjustment.
