Performance analysis of narrowband beamforming using fully and partial adaptive beamformers with a spherical array
This research proposes an improved narrowband partial adaptive beamformer analysis using a proposed spherical array. Comparison between the fully and the partial adaptive beamformers is given. The study is per...

Room Acoustics Analysis Using Circular Arrays: A Comparison Between Plane-Wave Decomposition and Modal Beamforming Approaches
A complete room acoustics analysis requires not only measurements of the single-room impulse response, but also a rigorous analysis of the sound field’s spatial properties. Angle-dependent information for the ...

Cancellation of Powerline Interference from Biomedical Signals Using an Improved Affine Projection Algorithm
Powerline contamination of recorded signals represents a major source of noise in electrophysiology and impairs the use of recordings for research. Furthermore it degrades the signal quality and overwhelms tin...

Robust Volterra Filter Design for Enhancement of Electroencephalogram Signal Processing
Electroencephalogram (EEG) recordings often experience interference by different kinds of noise, including white, muscle, and baseline, severely limiting its utility. The recent research has demonstrated that ...

Neural Networks Based Approach to remove Baseline drift in Biomedical Signals
Nowadays there exist different approaches to cancel out noise effect and baseline drift in biomedical signals. However, none of them can be considered as completely satisfactory. In this work an artificial neu...

Sample Entropy Analysis of Electrocardiograms to Characterize Recurrent Atrial Fibrillation
In a substantial number of patients atrial fibrillation (AF) recurs after successful electrical cardioversion, but at present there are no reliable clinical markers for confidently identifying the patients in ...
