【摘要】:針對鐵路GSM-R通信系統(tǒng)所需的高可靠性和高傳輸質(zhì)量的特性,通過對GSM-R受干擾情況的建模與分析,歸納并得出了3種常見GSM-R干擾的干擾模型,并基于此提出了一種基于通信信號與底部噪聲兩個層次的快速干擾識別方法及對應(yīng)的判定方法。相對以往的識別與判定流程,該方法具有較低的計算復(fù)雜度,使得快速地發(fā)現(xiàn)干擾、識別干擾更加容易實現(xiàn),且更有益于進一步的定位干擾與消除干擾。
[Abstract]:Aiming at the characteristics of high reliability and high transmission quality of railway GSM-R communication system, through modeling and analyzing the interference of GSM-R, three kinds of interference models of common GSM-R interference are concluded and obtained. Based on this, a fast interference identification method based on the two levels of communication signal and bottom noise and its corresponding decision method are proposed. Compared with the previous identification and decision flow, the proposed method has a lower computational complexity, which makes it easier to detect interference and identify interference, and is more beneficial to further localization interference and interference elimination.
