摘要
数字化转型背景下,中波广播技术正经历深刻变革,从传统模拟信号向数字信号传输模式转变。本文通过系统化研究,对比分析数字化转型前后信号覆盖范围、传输质量及能源消耗等关键指标。研究结果表明,数字化转型可以显著提升信号传输稳定性,扩大有效覆盖范围。此外,针对高原地区特殊地理环境,优化数字调制方案,改进天线匹配技术,在提升信号质量的同时降低系统能耗,可以为中波广播数字化建设积累宝贵经验。
Under the background of digital transformation,medium wave broadcasting technology is undergoing profound changes,changing from traditional analog signal to digital signal transmission mode.Through systematic experimental research,key indicators such as signal coverage,transmission quality and energy consumption before and after digital transformation are compared and analyzed.The results show that digital transformation significantly improves signal transmission stability and expands effective coverage.In view of the special geographical environment of plateau areas,the digital modulation scheme is optimized and the antenna matching technology is improved,which improves signal quality while reducing system energy consumption,accumulating valuable experience for the digital construction of medium wave broadcasting.
