摘　　要：连续相位调制(Continuous Phase Modulation,CPM)作为一种高效调制方式,因其包络恒定、相位连续等特点广泛应用于电台、数据链和卫星通信,但是在散射通信中的应用研究开展较少,尤其是缺少CPM散射通信系统级的设计与仿真。因此,针对散射通信特点提出一种基于CPM的串行级联通信系统,详细阐述了调制、解调、编译码、分集方式、相位同步等的实现和仿真参数的选择,在高斯及散射衰落信道下对设计的系统进行了性能仿真,验证了该系统设计的可行性及散射通信的适用性。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.
