【摘要】：隨著移動(dòng)通信系統(tǒng)的增多,室內(nèi)分布系統(tǒng)變得日益復(fù)雜,多系統(tǒng)合路造成的干擾也更加嚴(yán)重,針對(duì)室內(nèi)分布系統(tǒng)中的干擾問(wèn)題進(jìn)行研究。首先分析了室內(nèi)分布系統(tǒng)中的干擾問(wèn)題和產(chǎn)生的主要原因,定位了功率和互調(diào)兩大類干擾。針對(duì)主要的互調(diào)干擾和功率容限干擾進(jìn)行了深入的分析和研究,給出了干擾產(chǎn)生的原理、成因和對(duì)系統(tǒng)性能的影響,制定了干擾排查流程來(lái)精確定位干擾的類別和成因。針對(duì)不同的干擾類別制定出基于高性能器件的室內(nèi)干擾解決方案,保證室內(nèi)分布系統(tǒng)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.
