Coded performance of frequency-hopped MFSK communication systems on Rayleigh fading channels

A frequency-hopped multilevel frequency shift keying (FSK) modulation technique is employed in a mobile radio communication system, and its bit error probabilities are used with the number of users and repetitions as a performance measure. Bit error probabilities are calculated under the assumption that the probability of a multiple hit is negligible in comparison to the probability of a hit from only one signal. It is shown that the number of users can be significantly increased as the number of hopping frequencies becomes large at a low average bit error probability
