| Summary:
A novel wireless transmission scheme, as named the reconfigurable intelligent
surface (RIS)-assisted received adaptive spatial modulation (RASM) scheme, is
proposed in this paper. In this scheme, the adaptive spatial modulation
(ASM)-based antennas selection works at the receiver by employing the
characteristics of the RIS in each time slot, where the signal-to-noise ratio
at specific selected antennas can be further enhanced with near few powers.
Besides for the bits from constellation symbols, the extra bits can be mapped
into the indices of receive antenna combinations and conveyed to the receiver
through the ASM-based antenna-combination selection, thus providing higher
spectral efficiency. To explicitly present the RASM scheme, the analytical
performance of bit error rate of it is discussed in this paper. As a trade-off
selection, the proposed scheme shows higher spectral efficiency and remains the
satisfactory error performance. Simulation and analytical results demonstrate
the better performance and exhibit more potential to apply in practical
wireless communication.
