In this paper, we investigate wideband noise reduction based on zero phase signal analysis.
The zero phase signal is defined as the IDFT of amplitude spectra without phase spectra.
The zero phase signal hence represents the periodicity of the amplitude spectra.
We have proposed white noise and impulse noise reduction method as an application of the zero phase signal analysis.
In this paper, we show that the zero phase signal analysis is available a general wideband noise reduction. |
