摘　　要：基于高效调制技术的军事卫星跳频通信系统的应用已经越来越广泛。该文将当前军事卫星通信中广泛运用的高效调制方式GMSK与跳频技术相结合,搭建了SFH/GMSK卫星通信系统模型,并在其中加入卷积编码以改善系统性能,最后对系统模型结合一定的干扰条件进行仿真分析。对SFH/GMSK通信系统的研究,对军事卫星通信中的高效传输技术的研究有重要的参考价值。The application of the military satellite frequency hopping communication system based on efficient modulation technique has become increasingly widespread.In the paper it combines the effi-cient modulation GMSK widely used in the current military satellite communication with frequency hop-ping technology,builds a SFH/GMSK satellite communication system model,and also convolutional code will be adapted to improve system performance.Finally,the system model simulation analysis under cer-tain interference conditions will be presented.The research of SFH/GMSK communication system has an important reference value for the research of efficient transmission technology in military satellite com-munications.
