多径衰落是造成数字微波通信系统中断的主要原因,所以世界范围内主要从事数字微波通信的公司和研究单位都投入了较大的力量调查、研究,分析多径衰落对数字微波通信系统造成的影响,以便采取有效的对抗措施。本文着重介绍水电部在国内首次调查发生多径衰落时数字微波通信系统性能劣化的测试情况,在理论分析的基础上得到了初步的调查结论。
Multi-path fading is the main reason for the interruption of digital microwave communication systems. Therefore, companies and research institutes that are mainly engaged in digital microwave communication all over the world have devoted themselves to investigating, studying and analyzing the impact of multipath fading on digital microwave communication systems Influence in order to take effective countermeasures. This article focuses on the Ministry of MEW in the first survey of multi-path fading digital microwave communications system performance degradation of the test case, the theoretical analysis based on the preliminary findings.
