Analysis Of Electromagnetic Interference Between Wireless Devices On Different Vehicles Of Multi-vehicular Communication System

Electromagnetic interference between wireless communication devices of typical multi-vehicular communication system is studied in this thesis. First the basic theory of the propagation of electromagnetic wave applicable to analyze electromagnetic interference between wireless devices is introduced. Second the coupling interference model between wireless devices is presented, and based on three typical geographies, a simple and reasonable model of the propagation of electromagnetic wave is established, based on which several cases are presented and the limit distance of vehicles without electromagnetic interference is presented, and an important conclusion about electromagnetic interference between wireless communication devices on different vehicular is obtained. Furthermore, by abstracting and predigesting the actual communication vehicles and by means of MOM and simple replaceable method, a more exact field intensity of antennae is given, a method to analyze field intensity of antennae on multi-vehicular system in complex geography is presented. At last, the analysis software of EMC of vehicular multiple antennae system is developed, which is based on the thought of Object-Oriented Programming.
