Wavelet noise removal from baseband digital signals in bandlimited channels
This paper investigates the application of wavelet noise removal techniques to digital baseband signals. Non-linear filtering in the wavelet domain is used to improve the performance of the standard time domain correlation process for these signals. The proposed wavelet-based receiver computes the normalized cross correlation between the filtered wavelet coefficients of the received signal and wavelet coefficients that correspond to the known transmitted digital signals. Simulations are conducted comparing the wavelet receiver to the classical matched receiver.
