摘要
IP微波技术是一种全新的传输技术,它将IP技术运用到微波领域中传输数据信号,具有部署速率快、安装灵活、转运方便、传输数据高效等优势,成为我国常用的地面大容量无线传输系统。提出了一种微波传输的环境模型并对其进行了说明和讨论,该模型使用IP网络作为回传,有助于开发无线接入系统的通用网络。对超高频波段微波/互联网协议(IP)转换网络接口进行了原型设计,并对转换网络接口的三大功能模块进行了详细说明,实现了数字宽带综合业务的单向传输,并对地面传输信号(DTMB)进行了演示。结果表明,地面传输信号(DTMB)可以在IP网络上高效传输,并且间歇传送用于监测/观测应用的截断微波信号会显著降低网络所需的吞吐量。
IP microwave technology is a new transmission technology,which uses IP technology to transmit data signals in the microwave field.It has the advantages of fast deployment rate,flexible installation,convenient transport and efficient data transmission,and has become a common ground wireless transmission system with large capacity.An environmental model of microwave transmission was proposed and discussed.The model used IP network as the return transmission,which was helpful for the development of general network of wireless access system.The prototype design of UHF band microwave/Internet protocol(IP)network interface was carried out,and the conversion of the three major functional modules in the network were described,to realize the broadband integrated services digital transmissions.The results show that the ground transmission signal(DTMB)can efficiently transmit on the IP network,and the monitoring/truncation of the microwave signal can significantly reduce the network throughput as needed.
