As a new case of Light Detection and Ranging (LiDAR), full-waveform LiDAR records the complete waveform of backscattered echo of targets in certain time interval using high-speed data acquisition device. Since the full-waveform signal is generally short in length and badly contaminated by noise, it is rather difficult to find a method suitable for the signal filtering. In this paper, the Empirical...
The oscillation frequency of a combustion flame that is directly measured from the spectrum of a flame signal often depends on the level of white noise in the signal and the sampling rate. As long as the signal contains white noise, the "true" value of the oscillation frequency will never be known. However, the effect of the white noise and sampling rate on oscillation frequency measurement...
In this paper a new time-domain method using multi-rate signal processing techniques is presented for the removal of harmonic interference. The contaminated signal is first resampled to a higher but the nearest frequency that is an integer multiple of the base frequency of the harmonics. Down-sampling is then employed to divide the signal into a number of sub-sets. The harmonic interference appears...
