Signal Transformation for Effective Multi-Channel Signal Processing [PDF]
arXivElectroencephalography (EEG) is an non-invasive method to record the electrical activity of the brain. The EEG signals are low bandwidth and recorded from multiple electrodes simultaneously in a time synchronized manner. Typical EEG signal processing involves extracting features from all the individual channels separately and then fusing these features

A Bayesian Residual Transform for Signal Processing [PDF]
arXiv, 2014 Multi-scale decomposition has been an invaluable tool for the processing of physiological signals. Much focus in multi-scale decomposition for processing such signals have been based on scale-space theory and wavelet transforms. In this study, we take a different perspective on multi-scale decomposition by investigating the feasibility of utilizing a ...

Minimum Bit-Error Rate Design for Space-Time Equalisation-Based Multiuser Detection
, 2006 A novel minimum bit-error rate (MBER) space–time equalization (STE)-based multiuser detector (MUD) is proposed for multiple-receive-antenna-assisted space-division multiple-access systems. It is shown that the MBER-STE-aided MUD significantly outperforms

Spectral remapping of natural signals [PDF]
arXiv, 2019 Here we present an algorithm to procedurally remap spectral contents of natural signals. The algorithm takes in two inputs: a signal whose spectral component needs to be remapped and a warping or remapping function. The algorithm generates one output, which is a remapped version of the original signal.

YY Filter - A Paradigm of Digital Signal Processing [PDF]
Perspectives in Mathematical System Theory, Control, and Signal
Processing, pp. 331-340, Springer, 2010, 2013 YY filter, named after the founder Prof. Yutaka Yamamoto, is a digital filter designed by sampled-data control theory, which can optimize the analog performance of the signal processing system with AD/DA converters. This article discusses problems in conventional signal processing and introduces advantages of the YY filter.

Spatio-Temporal Deep Learning Models for Tip Force Estimation During Needle Insertion
, 2019 Purpose. Precise placement of needles is a challenge in a number of clinical applications such as brachytherapy or biopsy. Forces acting at the needle cause tissue deformation and needle deflection which in turn may lead to misplacement or injury. Hence,
