Abstract :
This study investigates how frequency offsets of multitone jamming affect the fast frequency-hopped binary frequency shift keying (FFH/BFSK) product-combining receiver (PCR) under additive white Gaussian noise (AWGN). We demonstrate the average bit-error-rate (BER) expressions of the FFH/BFSK PCR and the average BER expressions of an FFH/BFSK spread-spectrum (SS) communication system with frequency offsets of multitone jamming for the sake of understanding the simulation results better. Simulation results show that BER performance of the FFH/BFSK PCR with diversity under the worst case multitone jamming (MTJ) and AWGN suffers from multitone jamming´s frequency offsets when the jamming power is moderate, which is validated by several simulations with different frequency offsets configured in multitone jamming. Therefore, we can combat an FFH/BFSK PCR under multitone jamming with the help of frequency offsets of multitone jamming.
