Abstract

In several practical applications of the LMS algorithm, including certain VLSI implementations, the coefficient adaptation can be performed only after some fixed delay. The resulting algorithm is known as the delayed LMS (DLMS) algorithm in the literature. In this paper we consider a normalized version of this algorithm with a decreasing step size, μ(n), and discuss the almost sure convergence of the non-homogeneous algorithm, assuming a mixing input condition and the satisfaction of a certain law of large numbers.
