Fiber Optic Gyroscope Output Signal Processing Based on Multiwavelet Denoising

On the basis of properties of FOG output signal, the wavelet analysis has been used in suppressing the output noise of FOG. AR model of the FOG signal was constructed after wavelet de-noised processing finished and the parameters of the FOG output noise ...

Prefilters are generally applied to the discrete multiwavelet transform (DMWT) for processing scalar signals. To fully utilize the benefit offered by DMWT, it is important to have the prefilter designed appropriately so as to preserve the important ...

This paper discusses wavelet-based algorithm for audio denoising. We focused on audio signals corrupted with white noise which is especially hard to remove because it is located in all frequencies. We use Discrete Wavelet transform (DWT) to transform ...
