Five levels of discrete wavelet transform are applied to decompose the ECG beat signal into six subband components. Higher order statistics proceeds to calculate valuable features from the three midband components. These features together with three RR interval-related features construct the primary feature set. A feature selection algorithm based on correlation coefficient and Fisher discriminality...
The automatic tracking of components allows a quick and consistent analysis of parameters related to biological experiments. The register of parameters is done by a system that analyzes a sequence of images and computes a number of descriptors characterizing the behavior of each target. Our objective is to create a framework for tracking in biological experiments, with multiple targets that may suffer...
The paper first deals with the design of Rayleigh fading channel simulators based on a Moving Average (MA) model. We present a new approach to estimate the model parameters based on the inner-outer factorization. The core of the approach consists of assimilating an infinite-order MA model to the outer spectral factor of the channel power spectral density (PSD). This outer factor, which leads to a...
