| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Directivity control is an important issue in practical underwater optical communication (UWOC) due to the turbulence of the ocean. Underwater optical camera communication (UWOCC) is a low-directivity communication channel between an LED and a complementary metal oxide-semiconductor (CMOS) image sensor in a camera. Despite the considerable attention that OCC has received, little research has been conducted on equalization and demodulation of received optical signals in underwater environments. Therefore, this paper proposes a predictive equalization technique for UWOCC using color shift keying (CSK). The basic idea of the proposed equalization is to predict color shift in the color space considering the different attenuation of light intensity according to wavelength. We demonstrate the feasibility of the proposed predictive equalization in real-world environments including seas and lakes. Experimental results with 8 and 16 CSK transmissions confirm the feasibility of the proposed method. | |
