【摘要】：随着移动通信系统的增多,室内分布系统变得日益复杂,多系统合路造成的干扰也更加严重,针对室内分布系统中的干扰问题进行研究。首先分析了室内分布系统中的干扰问题和产生的主要原因,定位了功率和互调两大类干扰。针对主要的互调干扰和功率容限干扰进行了深入的分析和研究,给出了干扰产生的原理、成因和对系统性能的影响,制定了干扰排查流程来精确定位干扰的类别和成因。针对不同的干扰类别制定出基于高性能器件的室内干扰解决方案,保证室内分布系统性能。
[Abstract]:With the increase of mobile communication system, indoor distribution system becomes more and more complex, and the interference caused by multi-system combination is more serious. The interference problem in indoor distribution system is studied. Firstly, the interference problem in indoor distribution system and its main causes are analyzed, and two kinds of interference, power and intermodulation, are located. In this paper, the main intermodulation interference and power tolerance interference are analyzed and studied in depth, the principle of interference generation, the cause of formation and the influence on system performance are given, and the interference check flow is established to accurately locate the types and causes of interference. In order to ensure the performance of indoor distributed system, the indoor interference solution based on high performance devices is developed for different interference types.
