Analysis About Disturbance And Cupling Of Vehicular Communication System Based On Testing

Nowadays,to adapt to modern battlefield circumstances, army of various countries tries hard to develop its communications system to aspects integration, standardization, universalization and so on ,even to the vehicular communications system. However, the problem which electromagnetic compatibility (EMC) cause influences system work normally. Therefore the analysis and the simulation about altogether site disturbance of the radios that vehicular communications system carry on, have the vital significance to formulate the technology of suppresses.The article explains the two kind of working pattern that commonly used in the vehicular communications system: fixed-frequency, Direct Sequence Spread Spectrum (DSSS). On the foundation of carrying on the analysis models, it establishes analysis about disturbance and coupling of vehicular communication system based on testing. After obtain the testing data, it pretreated the primary signal. Using the theory of wavelet transformation reduce the noise of signal. Then profited from other discipline domain curvature withdraw the characteristic curve of transmitter. Based on above analysis models, compiled the co-site disturbance coupling analysis software. It showed that the simulation results is close to the actual result.Finally, by analyzing the results of simulation, the article gives some suppress measures to reduce the co-site disturbance. So,it provides engineering guidance for technical personnel, the superintendent, the operator, as well as the users of wireless...
