The detection of M-ary FSK signals in the wavelet domain (non-refereed)

This paper investigates the application of multi-resolution wavelet analysis to the problem of coherent detection of digital M-ary frequency shift keying (FSK) communication signals in additive white Gaussian noise (AWGN) channels.

Description
Summary:This paper investigates the application of multi-resolution wavelet analysis to the problem of coherent detection of digital M-ary frequency shift keying (FSK) communication signals in additive white Gaussian noise (AWGN) channels. The proposed wavelet-based receiver computes the normalized cross correlation between the filtered wavelet coefficients of the received signal and the wavelet coefficients that correspond to the known transmitted FSK signals. Simulations are conducted comparing the wavelet receiver to the classical coherent FSK receiver.
