摘要
本文结合岳阳市广播电视台广播电视节目信号传输用数字微波系统的建设案例,介绍了数字微波线路的主要技术要点、设计原则和技术方案,对微波传输系统的自由空间损耗、接收电平储备、线路传输干扰和波道衰落等影响传输可靠性的因素进行了计算或分析,可以为其他单位类似需求提供参考和借鉴。
This article combines the construction case of a digital microwave system for broadcasting and television program signal transmission at Yueyang Radio and Television Station to introduce the main technical points,design principles,and technical solutions of digital microwave links.It also calculates or analyzes the factors that affect the transmission reliability of microwave transmission systems,such as free space loss,receiver power margin,line transmission interference,and channel fading,which can provide reference and inspiration for similar needs of other units.
