随着通信行业的快速发展,移动通信对固定带宽内传输的信息容量的需求越来越大,而交调失真尤其是三阶交调,对信号容量以及接收灵敏度有着巨大的影响。文章主要对无线通信系统中三阶交调展开分析研究。首先阐述了三阶交调对通信产生的影响,然后分别从生产方面和施工方面着手分析了天馈系统对三阶交调性能的影响,最后介绍了避免三阶交调的一些方法。
With the rapid development of the communication industry, mobile communication needs more and more information capacity transmitted in a fixed bandwidth, and crosstalk, especially third-order intermodulation, has a tremendous impact on signal capacity and reception sensitivity. The article mainly analyzes and studies the third order intermodulation in wireless communication system. Firstly, the influence of the third-order intermodulation on the communication is expounded. Then the influence of the antenna-feeder system on the third-order intermodulation performance is analyzed respectively from the aspect of production and construction. Finally, some methods to avoid the third-order intermodulation are introduced.
