频分制多目标测量及通信系统中,进入接收机的信号多是等频率间隔的。在接收机非线性特性影响下,信号间将产生交调干扰频率分量,其中一些落在信号带内,难以通过滤波方法滤除。为克服交调干扰,应改善接收机有关部件的线性特性,直接抑制交调干扰频率的产生。本文仅对交调干扰频率分量的产生原因及其数量预以简单分析,供参考.
Frequency Division Multi-target measurement and communication systems, the signal into the receiver and more are the same frequency interval. Under the influence of the non-linear characteristic of the receiver, inter-signal interference frequency components will be generated between the signals, some of which fall within the signal band and are difficult to be filtered by the filtering method. In order to overcome the intermodulation interference, the linear characteristics of the receiver-related components should be improved to directly suppress the generation of intermodulation interference frequency. This article only on the crosstalk interference frequency component of the causes and the number of pre-simple analysis for reference.
