Partial Band Jamming Rejection of Differential Frequency Hopping System with Product-Combining Receiver Over Rayleigh-fading Channel

This paper presents a type of frequency-hopping system in HF (High Frequency) bands, which is called Differential Frequency Hopping (DFH) system. The frequency transition function (FTF) and the methods of signal detection are the key technologies for DFH system. The error-rate performances of DFH with Partial Band Jamming (PBJ) and additive white Gaussian noise (AWGN) over a Rayleigh-fading channel by using product-combining receiver (PCR) are studied analytically, the performances are validated by simulation results, performance comparisons among the various receivers show that the anti-jam (AJ) performance of DFH system with PCR outperforms that with linear-combining receiver (LCR).
