Research entails derivation of statistical description of output from an MFSK receiver which uses self-normalization of the output from quadratic detectors. The system uses fast frequency hopping to provide diversity and assumes independent channels for each hop when the signal is recombined. The effects of fading channels are investigated for both Rayleigh and Rician fading channel descriptions. Probability of bit error for the uncoded performance is plotted for various signal-to-noise ratios SNR and different levels of diversity versus worst-case partial-band jamming. Analysis for Forward Error Correction coding is included for rate 12 and 13 convolutional codes and n,k Reed-Solomon Block codes. Probability of bit error is plotted for each code with various signal-to-noise ratios and diversity levels 1 to 4 versus worst-case partial-band jamming.
