| 中文摘要: |
| 随着通信技术的飞速发展，高功率、宽频带、多载波技术成为通信系统发展的必然趋势。然而，无源器件产生的无源互调广泛存在于通信系统中，严重时互调产物落入接收频带将会导致整个系统的通信中断，这制约着通信系统向大带宽、大容量和高功率方向发展。因此，互调产物的抑制方法是实际工程应用中的研究焦点，是解决无源互调问题的关键所在。从无源互调现象的来源和互调干扰信号的特征出发，结合6G空天地海一体化通信背景，全面分析了无源互调干扰在空间通信、空基、船舰、地面等不同通信场景中的信号特征。从被动和主动干扰抑制两大方面对现有互调干扰抑制方法进行总结，以传统频带规划、工艺优化、器件结构优化为基础，拓展到非接触式设计、模拟抑制、基于信号处理和机器学习的抑制等先进抑制方法，为后续解决互调干扰提供思路和方案。最后，总结了无源互调干扰抑制技术的发展趋势。 |

| With the rapid development of communication technology, the inevitable trend in the development of communication systems is high power, wide bandwidth, and multi-carrier technology. However, passive intermodulation generated by passive devices exists widely in the communication system. Once the intermodulation products fall into the receiving band, the whole system will be interrupted. This phenomenon restricts the development of communication systems to the direction, which is equipped with large bandwidth, large capacity, and high power. Therefore, it is necessary to focus on the suppression method of intermodulation products in practical engineering applications. This paper comprehensively analyses the signal characteristics of passive intermodulation interference in different communication scenarios, such as space communication, air-based, ship, and ground, starting from the sources and characteristics of passive intermodulation and combining with the background of 6G air, sky, land and sea integrated communication. Existing intermodulation interference suppression methods are summarised from two major aspects of passive and active interference suppression, based on traditional band planning, process optimization, and device structure optimization, and expanded to advanced suppression methods such as non-contact design, analog suppression, signal processing and machine learning suppression, which provide ideas and solutions for the subsequent resolution of intermodulation interference. Finally, the development trend of passive intermodulation interference suppression technology is summarised. |
