摘要
文中通过对通信设备建模,对其接收装置进行抗干扰性能分析,预测其在互调干扰及镜像干扰下的抗干扰性能,最后依据受扰结果对镜像干扰下的系统进行电磁加固。文中的分析方法可以预测电子系统在电磁干扰环境下的抗干扰性能,对优化系统设计具有指导作用。
A radio receiver has been modeled for system level performance analysis. The performance of the receiver under intermodulation and hermitian image interferences was simulated and some valuable results were obtained. Also the design for overcoming the hermitian image interference was taken based on the simulated results. It is shown that the system level simulation is a useful tool to predict the performance of electronical systems in the environment of electromagnetism interferences, and is helpful to the design of electronical systems.
