Abstract

Free-space optical communication has recently garnered significant attention as a future-proof solution for high-speed wireless connectivity, not only serving point-to-point terrestrial links but also supporting intersatellite, satellite-ground, and deep-space communication applications. This paper reviews some technical challenges inherent to free-space optical communication systems and provides an overview of the recent state-of-the-art solutions developed to address the challenges.

자유공간 광통신 기술은 지상에서 두 지점 간 초고속 신호를 무선으로 전송하는 데에 활용되고 있을 뿐만 아니라 인공위성 간 통신, 인공위성-지상국 통신, 우주선과 지상국 통신 등에도 폭넓게 활용되고 있다. 본 논문에서는 자유공간 광통신 기술의 기술적 문제들과, 최근 발표된 기술들로 도달한 해결책을 소개한다.
