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-selective fading channel. The discrete-input continuous-output memoryless channel's~(DCMC) capacities…
