Abstract

In this paper, we propose dual-polarization technique which double the system capacity without increasing any other bandwidth. In theory, dual-polarization technique can double system capacity by using an orthogonal electromagnetic wave. However, cross-polarization interference and multipath interference degrade system performance in practice. To cope with this problem, we propose Cross Polarization Interference Canceller(XPIC) for ITS/DSRC system which can mitigate the XPI as well as multipath propagation interference. We also analyze and discuss its performance with relevant computer simulation results.

본 논문에서는 ITS/DSRC시스템에서 동일 대역을 유지하면서 시스템 용량을 두 배로 증가시킬 수 있는 방법으로 이중편파(dual-polarization)기법을 제안한다. 이중편파기법은 상호 직교하는 전자기파를 이용하여 정보를 전달하는 방식으로 이론적으로 시스템 용량을 배가시킬 수 있다. 그러나 실제로는 XPl(Cross Polarization Interference)와 다중경로 간섭 등의 요인으로 시스템 성능 열화가 발생하는데 XPI 및 다중경로 간섭을 동시에 제거 가능한 XPIC(Cross Polarization Interference Canceller)를 해결책으로 제시하고 컴퓨터 시뮬레이션을 통해 이를 검증한다
