The Study on the Modeling Method of Blocking Interference Response of Wireless Receiver

分析了无线电接收机产生阻塞干扰的机理,讨论了阻塞干扰引起的接收机信噪比下降理论计算方法,介绍了阻塞干扰的测试方法,研究了利用测试数据建立阻塞干扰预测模型的建模流程及其应用流程,分析了实际阻塞干扰预测模型与理论模型存在差异的原因,利用研究成果建立了某型电台的阻塞干扰预测模型。

The paper analyzed the mechanism of blocking interference response of wireless receiver. The theoretical model of blocking interference response has built. And the paper discussed the test method of such response of receiver, and also analyzed the influence on test datum of key parts of receiver. The paper presented a blocking interference response modeling method with test datum, and then modeled a actual blocking interference response models of a certain wireless receiver, and introduced how to predict the blocking interference response with these models.
