基于虚拟无线电仿真平台，对中频噪声调幅干扰的统计特性进行理论分析，并对实验干扰数据进行统计特性估计，在此基础上进一步研究了语音中频段抗干扰算法。

Based on the virtual radio simulation platform, the statistics characteristics of noise AM(amplitude modulation) interference in IF (intermediate frequency) band is studied in this paper. The statistics characteristics of the real experimental data is estimated. The interference reduction algorithms in IF band are studied on the basis of theory research.
