Study of Fast Frequency Hopping Spread Spectrum and Jamming Systems

Abstract- Frequency hopping spread spectrum is an efficient technique to combat jamming.. In this paper we analysis the effect of partial band noise jamming in Fast Frequency hopping spread spectrum system. We consider a communication system that transmits MFSK over a channel. The partial band noise interference is model as AWGN Channel using the phase analysis method. We consider (ρ) as a worst case partial band noise fraction and Pb is bit error rate probability for given m and signal to noise ratio.
