As an efficient modulation method,Continuous Phase Modulation(CPM)is widely used in radio,data link and satellite communication due to its continuous phase,constant envelope and other characteristics.However,there is little research on its application in troposcatter communication,and especially there is a lack of CPM troposcatter communication system-level design and simulation.Therefore,having the characteristics of scattering communication considered,a serially concatenated communication system based on CPM is proposed,and the modulation,demodulation,encoding and decoding,diversity methods,phase synchronization and simulation parameters are elaborated.Then,the performance simulation is conducted for the system in Gaussian and troposcatter fading channels,verifying the feasibility of the system design and the applicability of troposcatter communication.
