SLIPT-Enabled Ground-to-UAV FSO Systems with Optical Reconfigurable Intelligent Surfaces
Luna Sugiyama, Phuc V. Trinh, Shinya Sugiura
This paper proposes an optical reconfigurable intelligent surface (ORIS)-assisted ground-to-unmanned aerial vehicle (UAV) free-space optical (FSO) communication system empowered by…
Denoising-Autoencoder-Assisted Physical Layer Secret Key Generation
Zhengyu Xu, Shun Kojima, Shinya Sugiura
In this paper, we propose denoising autoencoder (DAE)-assisted secret key generation (SKG), where channel noise reciprocity imperfections induced due to wireless channel measuremen…
Iterative Optimization of Reconfigurable Intelligent Surface Aided Single-Carrier Spatial Modulation
Kentaro Nagaya, Shinya Sugiura
This paper proposes a novel cyclic-prefixed single-carrier transmission scheme that amalgamate a reconfigurable intelligent surface (RIS) with spatial modulation in the frequency-s…
Reduced-Overhead Channel Estimation and Iterative Detection of FTN Signaling Based on Pilot Superimposition and Spectral Interference Alignment
Yuchen Wu, Shinya Sugiura
This paper proposes low-overhead and low-complexity channel estimation (CE) of frequency-domain equalization aided faster-than-Nyquist (FTN) signaling. In the proposed CE scheme, t…
Exploiting Skyrmions in Free-Space Optical Communication
Ryosuke Hara, Satoshi Iwamoto, Shinya Sugiura
In this paper, we propose a novel free-space optical (FSO) communication system utilizing optical skyrmions. We introduce a scheme referred to as skyrmion number modulation (SkM),…
