This paper presents a new HF frequency hopping communication system which is called correlated hopping enhanced spread spectrum (CHESS).The composition of CHESS is discussed.Differential frequency hopping (DFH) which is the key technology in this system is described and the performance of DFH is analyzed.The paper also gives the simulation results of different demodulation algorithm.According to the characteristic of DFH,the new demodulation algorithm using frequency sequence detection is presented and its performance is analyzed and simulated.
