An exact performance analysis of the clipped diversity combining receiver for FH/MFSK systems against a band multitone jammer

This paper applies the clipper receiver with diversity combining techniques to the frequency hopping (FH) M-ary frequency shift keying (MFSK) systems against a destructive band multitone jammer, and presents an exact error probability performance evaluation with further discussions. A noise free channel is first assumed for analysis, and this assumption is then verified by computer simulation. Both optimal jamming tone power from the jammer's view and the choice of the clipping level from the communicator's view are investigated. The worst case performance of the FH/MFSK system against an optimum jammer is discussed in detail with extensive numerical results. It is also found that the clipper receiver provides the most attractive performance as compared to several other diversity combining receivers previously proposed.<
