Detection of frequency-hopped waveforms embedded in interference waveforms with noise [PDF]
2007 IEEE International Conference on Communications, 2007 The article of record as published may be found at http://dx.doi.org/10.1109/ICC.2007.494Bandwidth usage has become more complex such that it is not uncommon that multiple signals of appreciable power may be present within the same bandwidth.

Application of adaptive wavelet thresholding to recovery geoacoustic signal pulse waveforms [PDF]
EPJ Web of Conferences, 2021 Recorded geoacoustic signals often contain noise and interference. Their appearance is caused by various reasons, e.g. of propagation environment heterogeneity, weather condition influence, human activity, etc.

OTFS Waveform with Phase Noise in sub-THz
2022 IEEE 96th Vehicular Technology Conference (VTC2022-Fall), 2022 The availability of large bandwidths in the sub-THz bands appears to be a solution for increasing the capabilities of future wireless communication technologies. However, phase noise (PN) generated by oscillators in this band generates significant signal distortion which need to be addressed. In this paper, we study the impact of PN on OTFS. We propose

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 ...

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.
