Paper, 2002Beskrivning: 9 sÄmnen: Bibl.nr: VTI 2002.0071Location: Abstrakt: In order to evaluate the influence of snow on the radio propagation of Dedicated Short Range Communication (DSRC) systems, received power and Carrier-to-interference (C/I) power ratio characteristics were analyzed with the ray trace method by changing the height of roadside walls and materials for road surfaces and roadside walls into concrete, wet snow and dry snow. The reflection coefficient was a crucial parameter to this analysis. The result of analysis was also compared with the experimental data. It was clarified that though dry snow hardly affects the radio propagation, wet snow affects the received power characteristic near the desired BS, and wet snow reduces the communication area where the C/I performance exceeds the required threshold level of the DSRC systems.| Aktuellt bibliotek | Status | |
