Method to Solve Underwater Laser Weak Waves and Superimposed Waves
Sensors, 2023 With the rapid development of Lidar technology, the use of Lidar for underwater terrain detection has become feasible. There is still a challenge in the process of signal resolution: the underwater laser echo signal is different to propagating in the air,

Costas DFC-Based Random Stepped Wideband Waveform for Interference Countermeasure in SAR Imagery
Sensors, 2022 Interference in SAR imagery will induce false targets or form a mask in specific areas to prevent accurate scene assessment. Traditional anti-jamming methods based on waveform agility require a trade-off between anti-jamming performance and imaging ...

Scalable decomposition of speech waveforms
Speech Coding, 2002, IEEE Workshop Proceedings., 2003 Decomposition of speech signals into periodic and noise components is widely used in speech coding to facilitate efficient compression. Existing decomposition schemes are too inflexible to model transient changes in the speech signal, require high delay or produce a large parameter set that is not scalable to low rates.

Denoising for satellite laser altimetry full-waveform data based on EMD-Hurst analysis
International Journal of Digital Earth, 2020 Full-waveform decomposition is crucial for obtaining accurate satellite-ground distance, the accuracy of which is severely affected by noises. However, the traditional filters all depend on filtering parameters.
