摘要
MMDS是Multi-channel Microwave Distribution System的简称,
即多路微波分配系统。作为CATV联网的重要手段之一,MMDS具有
投资少、建网快、可靠性高、覆盖面广等特点,在世界各地如雨后春
笋般的兴起。在此情况下,如果不进行科学的系统规划,MMDS将难
以达到预期效果。
本文将就MMDS的系统规划以及信号中继展开研究,并就困扰
MMDS的同频干扰问题提出有效的解决方案,最后讨论对MMDS的
核心——发射系统的优化设计。
MMDS is the shortened form of Multi-channel Microwave Distribution System. As an important means to build CATV network, MMDS is characterized by less investment., faster building.. higher reliability and wider coverage area, so it springs like mushrooms worldwide. In such situation, MMDS can not get the expected effect without scientific system programming.
In this paper, system programming of MMDS and signal relay will be discussed, and effective methods will be brought forward to resolve the problem of the interfere of the same .frequency which disturbs MMDS, in the last part there will be a discussion about the optimization design of the core of MMDS the transmission system.
