Multi-objective optimization method for coil current waveform of transcranial magnetic stimulation
Heliyon, 2023 Transcranial magnetic stimulation (TMS) has been proved to be effective in the treatment of many kinds of mental diseases. However, the clicking noise produced by the pulse current with large amplitude and short duration in the TMS coil may damage the ...

Effects of noise suppression and envelope dynamic range compression on the intelligibility of vocoded sentences for a tonal language [PDF]
, 2017 Vocoder simulation studies have suggested that the carrier signal type employed affects the intelligibility of vocoded speech. The present work further assessed how carrier signal type interacts with additional signal processing, namely, single-channel ...

Jammer-Nulling Transmit-Adaptive Radar Against Knowledge-Based Jammers in Electronic Warfare
IEEE Access, 2019 The authors present transmit-adaptive jammer nulling waveforms in cognitive radar (CRr) for aircraft response recognition as a form of electronic support in the electronic warfare domain. New forms of knowledge-based noise jammers that function as a form

Counter-Interception and Counter-Exploitation Features of Noise Radar Technology
Remote Sensing, 2021 In defense applications, the main features of radars are the Low Probability of Intercept (LPI) and the Low Probability of Exploitation (LPE). The counterpart uses more and more capable intercept receivers and signal processors thanks to the ongoing ...

Detection of Frequency-Hopped Waveforms Embedded in Interference Waveforms with Noise
2007 IEEE International Conference on Communications, 2007 Bandwidth usage has become more complex such that it is not uncommon that multiple signals of appreciable power may be present within the same bandwidth. The presence of multiple signals in addition to additive white Gaussian (AWGN) increases the difficulty of detecting frequency-hopped (FH) waveforms.

Interaural coherence for noise bands: Waveforms and envelopes [PDF]
The Journal of the Acoustical Society of America, 2010 This paper reports the results of experiments performed in an effort to find a formulaic relationship between the interaural waveform coherence of a band of noise γW and the interaural envelope coherence of the noise band γE. An interdependence described by γE=π/4+(1−π/4)(γW)2.1 is found.

Use and Abuse of the Fisher Information Matrix in the Assessment of Gravitational-Wave Parameter-Estimation Prospects [PDF]
, 2007 The Fisher-matrix formalism is used routinely in the literature on gravitational-wave detection to characterize the parameter-estimation performance of gravitational-wave measurements, given parametrized models of the waveforms, and assuming detector ...
