Bit error performance analysis of FH/MSK system in different multi-tone noise jamming

Considering the effect of the signal noise ratio (SNR) and signal jamming ratio (SJR) parameters on the frequency hopped minimum-shift keying (FH/MSK), the bit error ratio (BER) expressions are deduced under the environment of multi-tone jamming combined with background noise. When the SJR is lower than an inflexion which is around 10 dB, the BER is dominated by the multi-tone jamming mode, and the SNR affect BER less. When the SJR is in the high level, i.e. more than 10 dB, the background noise is the key factor to the BER. Furthermore, after comparing the error performance of three kinds of multi-tone noise jamming which are Poisson noise, Rayleigh noise, and additive white Gaussian noise (AWGN), the simulation results demonstrate that the AWGN generates higher bit error ratio, and the multi-tone jamming additive white Gaussian noise is the optimal jamming mode
