本文在分析阻塞点的基础上,提出求互调子扰抑制比、寄生响应(半中频响应)抑制比及7阶A-B响应的新概念和计算方法与其软件实现。它巧妙地指明阻塞点与抑制比的內在关系,这将使人们对移动通信中无线电接收机抗千扰性的研究与提高,提供新的启示,具有实用价值。 Based on the analysis of blocking points, a new concept and calculation method and its software implementation are proposed to find the suppression ratio of intermodulation, parasitic response (half-IF response) rejection ratio and 7-order A-B response. It cleverly points out the inherent relationship between blocking point and suppression ratio, which will provide people with new insights into the anti-jamming of radio receivers in mobile communications and have practical value.
