Performance Analysis of Broadband Frequency Sweeping Jamming for FH/MFSK Systems

The minimum resolution of the broadband frequency sweeping jamming (BFSJ) bandwidth is set to 1/M of the MFSK signal bandwidth, theoretical derivation of the anti-jamming performance for FH/MFSK systems in noise-free environment and additive white Gaussian noise (AWGN) channels are derived, respectively. The closed-form expressions of bit error rate (BER) are given and validated by computer simulations. The theoretical and simulation results show that the minimum resolution of jamming bandwidth has more influence on the BER performance when the jamming bandwidth becomes smaller. With the increases in the sweeping rate, the BER performance decreases under the given power of sweeping jamming and the bandwidth over AWGN channels.
