摘　　要：低轨卫星网络因其覆盖范围广、延迟低而成为现代通信的重要组成部分。然而,动态信道条件对通信质量的影响使得传统调制解调技术面临挑战。文章通过分析现有自适应调制解调方案的不足,提出了一种基于实时信道评估的自适应调制方法并优化了解调算法,旨在提高低轨卫星网络中的数据传输效率和可靠性,为低轨卫星网络的应用提供技术参考。Low orbit satellite network has become an important part of modern communication because of its wide coverage and low delay.However,the influence of dynamic channel conditions on communication quality makes the traditional modulation and demodulation techniques face challenges.In this paper,an adaptive modulation method based on real-time channel evaluation is proposed to improve the efficiency and reliability of data transmission in low-orbit satellite networks,and to provide technical reference for the application of low-orbit satellite networks.
