At Allerton'89 a Frequency-Hopped M-ary Frequency-Shift-Keyed Spread-Spectrum Communication System was introduced and the design procedure for the system operating over a Factory Radio Channel was presented.The Rayleigh fading was considered.In this paper,the error performance of the system operating over Rayleigh,Rician,and logNormal multipath fading for factory environments are investigated.The statistics of these channels,obtained from a recent channel model,are used to evaluate the performance of the FH-MFSK system.The average Bit Error Rate (BER) is formulated and evaluated numerically using IMSL Routines.The number of simultaneous users in terms of number of hopped frequencies,number of MFSK chips,receiver threshold,signal-to-noise ratio and channel statistics at a fixed BER for the channels are determined.
