Howtosignalprocessing
Spectral Whitening (sometimes called balencing or broadening) is a process usually applied post-migration to improve the resolution and appearance of seismic data and is a crude attempt to correct for frequency attenuation.
What is whitening of a signal?
The whitening process is often used for ambient vibration data before stacking waveforms for cross-correlation. The process is simple as Fourier transforming the signal after applying Hann window, then normalizing its magnitude, and then inverse Fourier transforming it.
What is whitening in rf?
3 Principle of data whitening
In an RF system, transmitted data is grouped into packets. These packets may contain long sequences of 0's and 1's which can introduce a DC bias into the transmitted signal. A radio signal with a DC bias will have a non-uniform power distribution over the occupied channel bandwidth.
What does a whitening filter do?
Whitening filters are widely used across the spectrum of fields for signal whitening or noise pre-whitening where the data is modelled as a random vector or as a wide-sense stationary (WSS) process.
