摘　　要：为探讨自适应调制技术在广播通信中的应用及其优势,文章采用理论分析和实例研究相结合的方法,系统地研究了自适应调制技术在数字电视广播、无线广播、互联网广播以及卫星广播中的具体应用。研究结果表明,自适应调制技术通过动态地调整调制参数,能够显著提高广播通信系统的频谱效率,提升系统容量,同时提高链路的可靠性。特别是在信道条件不断变化的现代通信环境中,自适应调制技术的优势更为明显。然而,自适应调制技术的实际应用还面临许多挑战,例如,如何更准确地估计信道状态,如何在计算资源和算法复杂度之间取得平衡等。笔者建议,未来的研究需进一步优化自适应调制技术,以满足广播通信中对高效率和高质量的需求。In order to explore the application and advantages of adaptive modulation technology in broadcasting communication,the article adopts theoretical analysis and case study methods to systematically study the specific applications of adaptive modulation technology in digital television broadcasting,wireless broadcasting,internet broadcasting,and satellite broadcasting.The research results indicate that adaptive modulation technology can significantly improve the spectral efficiency,system capacity,and link reliability of broadcast communication systems by dynamically adjusting modulation parameters.Especially in modern communication environments where channel conditions are constantly changing,the advantages of adaptive modulation technology are more obvious.However,the practical application of adaptive modulation technology still faces many challenges,such as how to more accurately estimate channel state,how to strike a balance between computational resources and algorithm complexity,and so on.The article suggests that future research needs to further optimize adaptive modulation technology to meet the demand for high efficiency and quality in broadcast communication.
