DECODING OF THE FSK SIGNAL WITH NOISE AND DISTORTION WITH THE USE OF COEFFICIENTS OF THE TIME-FREQUENCY TRANSFORM

Dorota Rabczuk, Beata Pałczyńska, Ludwik Spiralski
Abstract:
The coefficients of wavelet packet decomposition of the signal represent the components of the instantaneous spectrum. For the FSK signal which consists of two instantaneous frequencies f0 + df and f0 - df thresholding and weighing of the absolute values of decomposition coefficients at properly selected nodes shows which of the two frequencies was present in the spectrum at a time interval. In the proposed algorithm more than one vector of coefficients represent each frequency for better distinguishing the instantaneous frequencies.
