摘要
设计了一种可以用于抑制干扰的接收机结构,从互信息的角度分析了该接收机设计的合理性。仿真表明,该调幅通信接收机在受到相同频率的调频、调幅噪声干扰时,可以有效地抑制干扰。
A new receiver scheme to resist jam is designed for improving the performance of communication under interference, whose validity is analyzed from the view of mutual information. Computer simulations show that this AM receiver sheme can resist interference when it is corrupted by co-frequency AM or FM（frequency modulation） jam.
