Comparative Review of the Algorithms for Removal of Electrocardiographic Interference from Trunk Electromyography

“…Adaptive filtering has been widely used for noise reduction in biomedical applications [ 30 , 31 , 32 , 33 ]. In general, an adaptive filter estimates the transfer function between a noise reference signal and the actual noise affecting the signal; any noise correlated to the reference signal is then removed from the raw signal [ 34 ].…”

Simulator of a Full Fetal Electrocardiogram Measurement Chain by Multichannel Capacitive Sensing

“…The significantly smaller amplitude of the fECG further increases the complexity of capacitive fECG measurements. In one of our previous studies, an adaptive filtering method was proposed for MA reduction in single-lead capacitive ECG recorded on adults [17]. This article builds on the same capacitive sensing principle as proposed in [17].…”

“…The simulator of the full capacitive fECG measurement chain is realized by integrating existing individual models [11], [14], [16], [17], whose scheme is shown in Fig. 1.…”

“…The aim of this article is, therefore, to investigate the feasibility of using capacitive electrodes for fECG measurements by dedicated in − sili co simulation. To this end, a multichannel simulator of a full capacitive fECG measurement chain is realized for the first time by integrating existing models that have been individually investigated by previous authors, such as the ECG model and the model of the capacitive sensors [11], [14]- [17]. The realized simulator generates multichannel capacitive fECG data with artificial MAs and system noise.…”

Multistage Attitude Determination Alignment for Velocity-Aided In-Motion Strapdown Inertial Navigation System with Different Velocity Models

“…Strapdown Inertial Navigation System (SINS) are now being widely used for position, location and navigation in both military and civil fields [1,2]. Nevertheless, SINS with integral operation is a dead-reckoning navigation system [3,4]. So it is necessary to research the system initialization, namely initial alignment, which is the precondition to guarantee the performance of navigation operation.…”
