摘　　要：通过对移动网络高干扰问题原因进行分类分析,利用FAS的频谱特征,提出一种基于FAS的基站频率测量的干扰规避方法,该方法利用叠加的互调信号在不同频点有不同干扰信号强度的特点,使高干扰的比例下降11.45%,高干扰小区处理平均时长由6.33天减少到1.5天。经验证,该方法可有效解决GSM网络和窄带物联网的外部干扰问题。By classifying and analyzing the causes of high interference problem in mobile networks,an interference avoidance method based on FAS’s Base Station frequency measurement is proposed.For this method,since the superposed intermodulation signals have different interference intensities at different frequency,the proportion of high interference is reduced by 11.45%,the average processing time in high-interference cells is reduced from 6.33 days to 1.5 days.It is proved that this method can effectively solve the external interference problem in GSM networks and narrow-band Internet of Things.
