| 研究開始時の研究の概要 |
Underwater optical wireless communication (UOWC) is considered a potential candidate for B5G/6G networks. The major hurdle for practical and reliable UOWC systems is the complex characteristics of the underwater channel that depend on changeful environments ranging from shallow coastal water to deep oceans.To overcome the dynamics nature of the UOWC channel, we propose a flexible and reconfigurable design of the UOWC system exploiting the concept of intelligent reflecting surfaces (IRS), the spatial diversity gain of the MIMO technique to meet the requirements of the underwater channel.
