N2 - This paper presents the tradeoff performance of the Slow Frequency Hopped Spread Spectrum Multiple Access (SFH-SSMA) communication system under conditions of multiple user interference (MUI) for a common communication channel. A Reed Solomon (RS) code with erasures for decoding are employed along with an orthogonal M-ary frequency shift keying (MFSK) modulation scheme, and a non-coherent demodulation. As more users are added the communication channel error probability will increase. The tradeoff between the communication system parameters of RS code rate, number of frequency slots available in the frequency hopping pattern, are optimized and analyzed. The optimization methods are based on maximizing the number of simultaneous transmissions of active users (K) and minimizing the bandwidth expansion factor without degradation of the channel performance reliability. Incomplete Beta approximation method was used in the analytical model. The simulation and analytical results show that, for a large number of simultaneous transmissions of active users, optimum utilization of a given channel capacity and minimum RF bandwidth expansion factor can be combined to optimize the channel performance reliability.
