%X This paper presents a new HF hopping system, which is called Differential Frequency Hopping (DFH) system. The frequencies transition function and the method of signal detection are the key technologies in this system. Detection and receiving symbol by symbol, detection by sequence and linear-combining receiving are two kinds of methods of signal detection and receiving. The performance of rejecting Partial Band Noise Jamming (PBNJ) by using these two methods is analyzed respectively in theory, and the corresponding simulation results are given, all these prove that the performance of DFH system with signal detection by sequence and linear-combining receiver is much better than conventional frequency hopping system under PBNJ.
