In this letter, the bit error probability of a hybrid DS/SFH-SS (Direct-Sequence/Slow-Frequency-Hopped Spread-Spectrum) system is derived for a Nakagami fading channel in the presence of multiple tone jamming. At a low JSR (jamming-to-signal power ratio), a pure DS-SS system can achieve lower bit error probability than a hybrid DS/SFH-SS system. But at a high JSR, a hybrid DS/SFH-SS system is shown to be superior to a pure DS-SS system. Especially, the worst case performance of a hybrid DS/SFH-SS system is almost equal to that of a pure DS-SS system.
