Abstract
자유 공간 광(free-space optics, FSO) 통신에서 에너지 수확은 태양 전지판(solar panel)을 이용한 광-검출기(photodetector)로 에너지를 수확하면서 동시에 통신을 할 수 있는 자유 공간 광 통신 시스템이다. 본논문에서는 자유 공간 광 통신을 이용한 무선 통신과에너지 수확(energy harvesting) 및 브로드캐스팅 릴레이 시스템에 대한 파워 할당과 보안 아웃티지 확률(secrecy outage probability) 분석하고 최적 파워 할당을 구해본다.
For energy harvesting in free-space optical communications, a solar panel is used as a photodetector. It is capable of simultaneous data transmission and energy harvesting in free-space optical communications systems. In this letter, we present secrecy outage performance of simultaneous energy harvesting and broadcasting relay system and provide an optimal power allocation at the relay.
