针对短波信道时变性强、衰落大、频段拥挤等一系列劣势导致的短波难以进行宽带传输的问题，提出了以知识图谱为核心的短波天波宽带传输算法，设计了基于先验知识的高效并行探测算法，阐释了基于知识图谱的传输参数动态优化方法。在短波天波一跳的实测结果表明，提出的短波天波宽带传输算法可以实现最高500 kb/s的峰值速率，为后续短波宽带通信技术的深入研究和工程化落地提供了有益的思路。

To address the challenges of wideband transmission in HF communications caused by the characteristic of time-varying channels, severe fading, and crowded spectrum, a knowledge-graph-based HF sky-wave wideband transmission algorithm is proposed.Firstly, a prior-nowledge-based parallel detection algorithm with high efficiency is proposed, then the method of knowledge-graph-based dynamic optimization of transmission parameters is illustrated.The test result of one-jump HF sky-wave transmission demonstrates that the proposed algorithm can achieve a peak data rate of up to 500 kb/s, providing valuable insights for further research and practical implementation of wideband HF technologies.
