Abstract-In this paper, we present a new approach to improve the acoustic echoes occurs in today's telecommunication system. We show that the new approach reduces the computational complexity; unlike old approaches like a LMS, NLMS and variable step size (VSS) algorithm, converges rate and misadjustment and computational complexity are biggest challenges for us. So new approach is known as DFVSS-NLMS algorithm and suitable candidate for a real world application.

Abstract-The echo cancallation is rapidly becoming a variable alternative to the conventional method of echo suppression. Echo cancallation using an adaptive filtering algorithm to model the echo path becouse impulse reponse is highly time varing and compute the replica of the echo component present in the speech signal. This research paper, we present the new optimized variable step size normalized least means sqaure algorithmin the context of acoustic echo cancellation. This new algorithm is design in such a way that the step size adjustment is controlled by using the suqaure of the means sqaure error and gives the unique minima of weight vector. New algorithm is suitable for real world application as compared to the old conventional adaptive algorithm.
