Abstract This paper presents a new frequency hopping system in HF (High Frequency) bands, which is called Differential Frequency Hopping (DFH) system. The frequency transition function and the method of signal detection are the key technologies in this system. The performance of DFH with partial band jamming and additive white Gaussian noise over the Rayleigh fading channel by using product-combining receiver is analyzed in theory, and the corresponding simulation results are given. All these prove that the anti-jam performance of DFH system with product-combining receiver is much better than that with linear-combining receiver.
