| 摘 要： | 本文针对TD-LTE网内干扰识别的难点问题，分析了目前IDS系统的TD-LTE网内干扰识别算法的准确率，然后选取并对比分析了同频邻区不同业务量指标与高干扰小区24小时底噪均值的相关系数，确定了与底噪相关性最强的业务量指标。在此基础上，本文提出了一种基于同频邻区业务量与底噪相关性的网内干扰识别算法，大幅提升了TD-LTE网内干扰识别准确率。

| Abstract: | This paper analyses the veracity of the inter-system interference recognition method of TD-LTE which has been used in IDS system and calculates the person correlation between traffic data and interference noise. Then this paper proposes an inter-system interference recognition method based on the person correlation between traffic data and interference noise which can effectively promote the veracity of the inter-system interference recognition and improve the interference optimization efficiency. |
