调频广播覆盖的影响因素与优化技术

Influencing Factors and Optimization Techniques of Frequency Modulation Broadcasting Coverage

为给调频广播的发展提供理论支持和实践指导,深入分析调频广播覆盖的影响因素,如发射功率、天线高度、地形地势、建筑物等,并提出增强发射功率、优化天线布局、地形适配传输及增强城区信号等优化技术,可以有效提升调频广播信号的传输质量,扩大其覆盖范围。

In order to provide theoretical support and practical guidance for the development of frequency modulation broadcast,this paper deeply analyzes the factors affecting frequency modulation broadcast coverage,such as transmission power,antenna height,terrain and topography,buildings,etc.,and proposes corresponding optimization technologies such as enhancing transmission power,optimizing antenna layout,terrain adaptive transmission,and enhancing urban signals,so as to effectively improve the transmission quality of frequency modulation broadcast signals.Expand its coverage.
