Abstract :
This correspondence studies the effect of a nonzero delay on the performance of the leaky LMS algorithm. The stability bound on the step size is derived for error convergence. It is shown that leakage allows for larger bounds on the step size of the delayed LMS algorithm. Theoretical bounds are verified by simulations
