Abstract

In this paper, we designed a diversity modem hardware architecture for IEEE802.11p WAVE and tested the modem on the road with car attached shark antenna. One of the dual channel modem and the diversity single modem with maximum ratio combining algorithm can be selected on the designed architecture. The designed modem have been implemented on the Xillinx Kintex7 FPGA. We tested the modem performance on the smart highway experience road. As experimental results, we can verify the performance of the diversity modem on real road and the enlarged communication range by more than 30%.

본 논문에서는 IEEE 802.11p WAVE 모뎀을 위한 다이버시티 모뎀 구조를 제안하고 설계하였으며, 이를 실차에 장착하여 성능테스트를 수행하였다. 제안한 구조는 듀얼채널과 다이버시티 기능을 선택적으로 수행할 수 있으며, 선택적 안테나 다이버시티와 Maximum Ratio Combining (MRC) 다이버시티 기능 중하나를 선택하여 수신할 수 있다. 개발된 구조는 HDL로 설계되어 Xillinx Kintex7보드를 이용하여 실도로에서 실차에 장착하여 테스트를 수행하여 성능을 검증하였다. 실험결과 개발된 다이버시티 모뎀은 단일 채널 모뎀에 비하여 안정적인 통신 성공률을 유지할 수 있으며, 전송거리도 30%이상 향상됨을 확인하였다.
