This paper investigates the Error Vector Magnitude (EVM) obtained using different parameters of Root Raised Cosine Filter (RRCF) for Visible Light Communication (VLC) front ends for M-QAM (M-ary Quadrature Amplitude Modulation) Broadband over Visible Light (BVL). The authors conducted a real measurement EVM using a modern modular PCI eXtensions for Instrumentation (PXI) measuring apparatus. This sophisticated...
The fetal electrocardiogram (fECG) extraction from the composite ECG signal recorded non-invasively is discussed. The main point of this paper is to introduce some of the most used Recursive least squares (RLS) based FIR Adaptive Filters, and to determine which of them is the most effective under varying circumstances. Experimental results suggest the optimal settings for the adaptive system useful...
The aim of this paper is evaluation of the best setting options for adaptive neuro-fuzzy interference system (ANFIS) in case of fetal electrocardiogram (fECG) elicitation from two ECG signals. Thoracic ECG (tECG) signal represents maternal ECG (mECG). Abdominal ECG (aECG) signal is a mixture of mECG, fECG and additive noises (e.g. power line interference, motion artifact, ambient noise…). While additive...
The extraction of the Fetal Electrocardiogram (fECG) from the composite Electrocardiogram (ECG) signal obtained from the abdominal lead is discussed. The main point of this paper is to introduce some of the most used Least Mean Squares (LMS) based Finite Impulse Response (FIR) Adaptive Filters and to determine which of them are the most effective under varying circumstances. Experimental results suggest...
The main objective of this work is creation of a synthetic ECG signal in software MATLAB based on the analysis of Fourier series. The individual elements of ECG signal are approximated by mathematical model, which is thoroughly described, explained and then applied. The output is a synthetic model of an ECG. Our approach to modeling biological signals allows change input parameters (amplitude and...
