摘　　要：为解决通信系统在实际应用中抗干扰能力弱、数据链性能低等问题,本研究在正交频分复用技术的基础上引入精确时间协议,形成精确时间协议—正交频分复用同步机制,并基于该机制提出新型抗干扰系统。测试发现抗干扰系统同步精度维持在75ns,且其能够在不同信噪比条件下有效降低误比特率。综上,本研究建立的抗干扰系统能够满足现代通信网络对高精度时间同步的需求,为通信网络的稳定运行提供技术支撑。To solve the problems of weak anti-interference ability and low data link performance in practical applications of communication systems,this study introduces a precise time protocol based on orthogonal frequency division multiplexing technology,forming a precise time protocol orthogonal frequency division multiplexing synchronization mechanism,and proposes a new anti-interference system based on this mechanism.The test found that the synchronization accuracy of the anti-interference system is maintained at 75ns,and it can effectively reduce the bit error rate under different signal-to-noise ratio conditions.In summary,the antiinterference system established in this study can meet the high-precision time synchronization requirements of modern communication networks and provide technical support for the stable operation of communication networks.
