Abstract :
An exact analysis is performed to find the probability of bit error for a multiple-access system using frequency-hopping multilevel frequency-shift-keying signals (FH/MFSK) in Rayleigh fading. Inherent frequency diversity is utilized at the receiver. The impact of the near-far problem on power differentials is studied, and improvements due to the use of soft-limiters at the receiver are shown as functions of the many parameters involved
