NOISE CANCELLATION WITH LMS VARIANTS

Abstract

The noise is one of the important factors that affect negatively the operation of circuits and systems. There are different methods and techniques for cancelling/reducing/de-noising these unwanted signals that mix with the original signal. In this study, an application/simulator that performs noise cancellation operations with least mean-squares algorithms was designed. The application, which has powerful visual support and a user-friendly interactive interface, can make single or comparative noise cancellation operations and performance analyzes with different algorithms on noisy signals. The effects of the algorithm parameters can be observed, information about the related algorithms can be obtained via the developed application that can also be used for educational purpose.
