实时频谱分析仪在同频干扰监测中的应用

针对同频干扰,提出了运用实时频谱分析仪从频谱角度实现在线干扰监测并进行干扰告警的思路。通过模拟中国移动对GSM-R系统的同频干扰场景,证明了实时频谱分析仪可以分辨出在不同时间上共享相同频率的较强信号下面的低幅度信号,并得到了其进行同频干扰分析时的幅度分辨能力和时间分辨能力。

Application of Real-time Spectrum Analyzers in Co-channel Interference Monitoring

To mitigate co-channel interferences, this paper presents an idea of utilizing real-time spec-trum analyzer to monitor the interference as well as report the interference warning. By simulating the co-channel interference scenario of China Mobile to GSM-R system, it is demonstrated that the real-time spectrum analyzer can figure out the weaker signal from the co-channel signals with the same carrier fre- quency in different time slots. And it is capable of recognizing amplitude and time when analyzing co-channel interference.
