Abstract
The present invention relates to an optical communication system and an optical transmission device. By changing the ratio between the first segment and the segment or/and the amplitude of the second segment, the digital signal is modulated and transmitted in the form of an optical signal. Then a solar panel, which is used as the receiver for the optical signal, can receive the optical signal and give directly the one or more digital signal without demodulation. Thereby, the costs of using a solar panel as the optical receiver may be reduced and the transmission rate may be enhanced.

13. An optical transmission device, comprising:
-
a modulation unit, configured for receiving one or more digital signal and outputting one or more modulated signal, said modulation unit reduces the amplitude of said second segment when said one or more digital signal is a high-level signal, and said modulation unit increases the amplitude of said second segment when said one or more digital signal is a low-level signal, wherein said one or more digital signal includes a first segment and a second segment; and a light-source unit, receiving said one or more modulated signal, and transmitting one or more optical signal according to said one or more modulated signal. - View Dependent Claims (14, 15, 16)
