Abstract :
In this paper, the effect of multitone jamming (MTJ) on an FHMA/MFSK system is investigated. The channel under consideration is a Rician fading channel, with AWGN included in the analysis. The system capacity is considered as an indicator of the system performance and is calculated for different situations. The capacity is shown to be affected by channel fading state. For no fading, the capacity is 188 users, while with Rician fading it is 108 users and it is 78 users when the fading is Raleigh. The effect of jamming total power was found to have a minor effect on the system capacity. The capacity is affected mainly by number of tones of the multitone jamming (q). When q=2.5% of the frequency hopping bins, the capacity will be 108 users. At q=33% of the hopping frequencies, the capacity decreases to 78 users. When q=50%, the capacity becomes very small (42 users only) compared to the no jamming case
