초록

이중 편파 안테나 시스템은 근거리 가시광 통신 채널 환경에서 통신하기 위한 기술로 연구되어왔다. 본 논문에서는 편파 회전각이 미정렬된 상황에서 편파 안테나 간 발생하는 간섭을 고려한 랜덤 변수의 확률 밀도 함수를 구하고, 오수신(outage) 확률을 분석하였다. 또한 편파 회전각이 미정렬된 이중 편파 안테나 시스템의 상한 전송 용량이 4.5324 bps/hz 임을 밝혔다.

Dual-polarization antenna system has been being researched for wireless communications under short range line-of-sight channel environments. In this paper, probability density function of signal-to-interference-ratio(SIR) for the dual-polarization antenna system is derived, and SIR outage is analyzed. It is shown that the upper bound capacity of a dual-polarization antenna system without polarization alignment is 4.5324 bps/hz.
