车载通信系统电磁兼容仿真研究

Study on Electromagnetic Compatibility Simulation of Vehicular Communication System

随着通信电子的发展,电磁兼容性已成为车载通信系统集成的重要指标,直接影响着整个系统的性能指标。本文结合电磁兼容对车载通信系统的性能影响,分析了车载通信系统的电磁兼容影响因素,建立了系统集成电磁兼容指标分配模型,并针对车顶天线布局、车内系统互连进行了仿真分析,为车载通信系统集成指标量化提供了一种方法和思路。

With development of communication electronics,EMC becomes an important index of vehicular communication system integration already,which effects performance index of whole system directly.Factor of effecting EMC of vehicular communication system is analyzed combining effect of EMC on performance of vehicular communication system.Index distribution model of system integrated EMC is established,and simulation and analysis aiming at roof antenna layout and system interconnection in vehicle is carried out,and this provides a method and idea for quantifying the integrated index of vehicular communication system.
