摘　　要：分析了现有数字通信抗干扰技术存在的局限性。在研究了盲源分离(Blind Source Separation,BSS)的理论基础上,介绍了一种基于盲源分离的数字通信抗干扰技术。建立了基于最大信噪比算法的盲源分离数字通信抗干扰传输模型,应用MATLAB仿真实现了2FSK通信信号与多种干扰信号的分离提取。仿真结果表明:应用基于盲源分离的抗干扰技术能够获得显著的抗干扰性能。The limitation of existing digital communication anti-jamming technology is analyzed.Based on BSS（blind source separation） theory,this paper describes a BSS-based anti-jamming technology of digital communication.The digital communication anti-jamming transmission model of BSS based on the maximum signal-to-noise radio algorithm is established,the simulation with MATLAB is done and the extraction of 2FSK com-munication signals from various jamming signal is realized.The simulation results show that the application of BSS-based anti-jamming technology could obtain remarkable anti-jamming performance.
