传播信道 meaning in Chinese
propagation channel
Examples
- Data broadcast is a new field of information service in recent years , it is a new dissemination tool and integrate the internet and broadcast television networks . its source can be from every web site , its channel is digital television , and it push all the content of the web site to customer ’ s computer . it has both the advantages of the two media above , just as has adequate signal source and can spread abroad
数据广播是近年来所兴起的信息服务的新领域,它整合了互联网和广播电视网,它可以取所有网站作信源,取数字电视做信道,把网站内容整体推送到家。它继承了前两种媒体的长处(信源丰富、传播广阔) ,又避免了各自的短处(传播信道拥挤、不能保存随时查看) ,是一种全新的文化工具。 - The ionosphere is a complex medium , which is aeolotropy , asymmetry , dispersive and changes randomly with time . in order to improve the communication quality of the shortwave that depends on the ionosphere , we should have aknowledge of the current condition of the ionosphere in real time . the backscatter sounding of high frequency can diagnose the real - time channel characters for shortwave communication or hf radar , which is great assistant to shortwave communication and hf radar
电离层是随机时变,各向异性,非均匀、色散的复杂介质。为了保证依赖于电离层进行的短波通信质量,必须了解电离层的实时状态信息。高频返回散射探测可以实时监测与短波通信或高频天波雷达相关的天波传播信道的状态,对短波通信和天波雷达工作起了重要的辅助作用。 - In chapter five , we first introduce the channel preferences about the propagation in an urban environment . then expand the past traditional analysis method about it . at last , we study the method of how to analysis it based on the results of the ray - tracing , and analysis a urban cell model
本文第五章，首先讨论了传播信道中重要信道参数的选取，阐述了传统分析方法，对基于射线跟踪结果的信道参数分析方法进行了研究，并对一个城市小区模型进行了具体的信道参数分析。
