Abstract

본 발명은, 전송 품질이 높은 고속통신이 가능한 가시광 통신시스템을 제공한다. 본 발명은, 다른 색의 빛을 발광하는 복수의 발광부를 가지며, 송신데이터를 색도 좌표상의 색도점에 대응시키고, 송신데이터에 대응하는 색도점의 색광이 방사되도록 각 발광부의 발광량을 산출하고, 채널 행렬의 추정에 이용하는 프리앰블 신호를 생성하고, 프리앰블 신호, 및 상기 산출한 발광량에 의거하여 각 발광부를 발광시키는 송신장치와, 다른 색의 광신호를 수신하는 복수의 수광부를 가지며, 프리앰블 신호에 대응하는 광신호가 각 수광부에서 수신되면 해당 광신호에 의거하여 채널 행렬을 추정하고, 상기 추정된 채널행렬에 의거하여 상기 색도점에 대응하는 광신호에 전파로 보상을 실시하고, 전파로 보상 후의 신호에 의거하여 색도좌표 상의 색도점을 검출하여 송신데이터를 복조하는 수신장치를 포함하는 가시광 통신시스템이 제공된다.
