针对铁路GSM-R通信系统所需的高可靠性和高传输质量的特性，通过对GSM-R受干扰情况的建模与分析，归纳并得出了3种常见GSM-R干扰的干扰模型，并基于此提出了一种基于通信信号与底部噪声两个层次的快速干扰识别方法及对应的判定方法。相对以往的识别与判定流程，该方法具有较低的计算复杂度，使得快速地发现干扰、识别干扰更加容易实现，且更有益于进一步的定位干扰与消除干扰。

In view of the characteristics of high reliability and high transmission quality which are needed in railway GSM-R communication system, by means of modeling and analysis of GSM-R communication system under the action of interferences, this paper summarized three common interference models on GSM-R communication system. On this basis, this paper proposed a rapid interference identification method and its corresponding determination method which is based on communication signal and bottom noise. Compared with other identification and determination methods, the method in this paper is of lower computational complexity, more helpful to achieve rapid interference identifying and determining, and more beneficial to interference locating and eliminating.
