Abstract: | Analysis is made of the effects of Doppler on the error rate performance of a low data rate binary FSK frequency hopping receiver, employing a discrete Fourier transform (DFT) technique for baseband detection. Bit detection decision is made by locating the maximum of the DFT outputs which, in the frequency domain, are assumed to be separated by 1/T where T is the bit period. Both the worst case and average error performances are obtained and presented as a function of Eb/N0 for various values of M where Eb/N0 is the signal bit energy-to-noise density ratio and M is the degree of freedom associated with the Doppler uncertainty window. The E b/N0 degradation as a function of M is also presented |
