Item Open Access Leakage analysis of the RSOR algorithm(Bursa Uludağ Üniversitesi, 2021-04-09) Hatun, Metin; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Elektrik Elektronik Mühendisliği Bölümü.; 0000-0003-0279-5508The RSOR algorithm is a recursive algorithm that has been proposed as an alternative to the RLS algorithm for updating adaptive filter parameters. As with other algorithms, the forgetting factor, filter length and relaxation parameter significantly affects the performance of the RSOR algorithm. In this study, using an adaptive FIR filter in system identification mode, the effect of forgetting factor, filter length and relaxation parameter on the leakage phenomenon of the RSOR algorithm was analyzed. For this purpose, firstly, the effect of measurement noise on the adaptive filter output, namely the leakage phenomenon, was explained analytically, and then the influence of the forgetting factor and other filter parameters on this leakage phenomenon was examined. The results obtained from the simulation studies are compared with similar algorithms.Item Open Access Noise cancellation with LMS variants(Bursa Uludağ Üniversitesi, 2021-02-02) Vatansever, Fahri; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Elektrik-Elektronik Mühendisliği Bölüm.; 0000-0002-3885-8622The 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 thisstudy, 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 thealgorithm parameters can be observed, information about the related algorithms can be obtained via the developed application that can also be used for educational purpose.
