Journal of Marine Science and Engineering, 2020 Altimeter waveforms are usually contaminated due to nonmarine surfaces or inhomogeneous sea state conditions. The present work aimed to present how the singular spectrum analysis (SSA) can be used to reduce the noise level in Jason-1 altimeter waveforms ...

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 ...

Inspiral-merger-ringdown waveforms of spinning, precessing black-hole binaries in the effective-one-body formalism [PDF]
, 2013 We describe a general procedure to generate spinning, precessing waveforms that include inspiral, merger and ringdown stages in the effective-one-body (EOB) approach.

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

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.
