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.

LMS Varyantlarıyla Gürültü Arındırma

Abstract

Devre ve sistemlerin işleyişlerini olumsuz yönde etkileyen önemli faktörlerden birisi de gürültülerdir. Orijinal işarete karışan bu istenmeyen işaretlerin arındırılması/azaltılması/temizlenmesi için farklı yöntem ve teknikler mevcuttur. Gerçekleştirilen çalışmada, en küçük karesel ortalama algoritmalarıyla gürültü arındırma işlemlerini gerçekleştiren bir uygulama/simülatör tasarlanmıştır. Güçlü görsel desteğe ve kullanıcı dostu etkileşimli arayüze sahip, eğitim amaçlı da kullanılabilen uygulama ile gürültülü işaretler üzerinde, farklı algoritmalarla tekli veya karşılaştırmaları gürültü arındırma işlemleri ve performans analizleri yapılabilmekte, algoritma parametrelerinin etkileri gözlemlenebilmekte ve ilgili algoritmalar hakkında bilgiler edinilebilmektedir.
