| 摘 要： | 同址干扰是车载、舰载、机载无线电通信中面临的一个重要问题,针对同址干扰对复杂通信系统的影响提出了一种有效的测试和分析方法;首先对车载电台的各种天线进行了耦合度测试,从实验和仿真两方面阐述了同址干扰的严重程度,为进一步定量分析同址干扰的影响,构建了有线测试平台;在需求分析基础上,详细介绍了平台的组成,并以短波、超短波电台为对象,通过大量现场实验,深入分析了误码率,同址工作电台的频率间隔和功率之间的相互关系;研究表明,同址干扰的定量分析是设计车载通信系统,合理分配电台工作参数的关键环节。

| Abstract: | The problem of co-site interference(CI) is important which vehicle,ship,and airplane's radio communication must face with.In order to evaluating the CI effect on complicated communication systems effectively,a testing and analysis method is proposed.First the coupling between all kinds of antenna on vehicular radios is measured,and the experiment and the simulation both illustrates the seriousness of CI,and to quantitative analysis of the CI effect,a line testing platform is constructed.On the basis of the ... |
