Adaptive FIR Filtering Using ABC Algorithm: a Noise Reduction Application on Mitral Valve Doppler Signal
Kockanat, Serdar; Koza, Turker; Karaboga, Nurhan; Logoglu, Ahmet (KAUNAS UNIV TECHNOLOGY, 2018)The Doppler signal of mitral valve is a biomedical signals and it is acquired by Doppler ultrasound device from mitral valve of hearth. It contains useful information about mitral valve and it can be used to diagnose mitral ... -
IIR Filter Paramater Estimation with ABC Algorithm for Mitral Valve Doppler Signal Denoising
Kockanat, Serdar; Koza, Turker; Karaboga, Nurhan (IEEE, 2015)Noise elimination is an important problem for biomedical signals like as mitral valve Doppler signals. In this work, mitral valve Doppler signal noise elimination realized with IIR filter. 4dB noise added mitral valve ... -
Noise Cancellation Application of ECG Signal Using Artificial Bee Colony Algorithm
Kockanat, Serdar; Koza, Turker; Karaboga, Nurhan; Erkoc, Murat Emre (IEEE, 2016)Electrocardiographic (ECG) signal is a biological signal that contains useful information about electrical activities of hearth. When obtaining ECG signals by using electronic equipment, there can be many distortions in ... -
Noise Cancellation on Mitral Valve Doppler Signal with IIR Digital Filter Using Harmony Search Algorithm
Kamislioglu, Bircan; Kockanat, Serdar; Koza, Turker; Karaboga, Nurhan (IEEE, 2013)In this paper, a filter design approach which uses the harmony search algorithm for additive white Gaussian noise cancellation through an infinite impulse response digital filter, is described. In the digital filter design, ... -
SSA Analysis of Noise Eliminated Transcranial Doppler Signals with IIR Filters
Koza, Turker; Karaboga, Nathan; Kockana, Serdar; Latifoglu, Fatma (IEEE, 2015)Biomedical signals affected with noise, interferences and other undesired effects like as Transcranial Doppler (TCD) Signals. In this work, 10dB additive White gaussian noise added on simulated TCD signals. Noise elimination ...
