Reconfigurable Intelligent Surface-Assisted Spatial Scattering Modulation

Xusheng Zhu et al.

Summary: This letter proposes a novel uplink millimeter-wave communication system that utilizes reconfigurable intelligent surface (RIS) and spatial scattering modulation (SSM) for improved data transmission over wireless channels. The system design includes reflecting phase shifters at the RIS to support two-hop communications, and a maximum likelihood detector for the RIS-SSM system along with a new analytical expression for tight union upper bound on bit error rate (BER). Monte Carlo simulations validate the accuracy of the analytical expression and demonstrate that the proposed RIS-SSM scheme achieves significantly lower BER compared to traditional SSM.

On the Performance of 3-D Spatial Modulation Over Measured Indoor Channels

Xusheng Zhu et al.

Summary: In this paper, a measurement-based three-dimensional spatial modulation system is proposed and its performance is studied through experiments. The results show that the existing channel model overestimates the performance of the system, and that the three-dimensional spatial modulation system outperforms the two-dimensional spatial modulation system under the same antenna array size.

Generalized Quadrature Spatial Modulation and Its Application to Vehicular Networks With NOMA

Jun Li et al.

Summary: The proposed generalized QSM (GQSM) scheme aims to increase the spectral efficiency of QSM by activating multiple transmit antennas in in-phase or quadrature domain, showing superior performance over traditional QSM in entire SNR region. Furthermore, collaborative GQSM with NOMA (C-NOMA-GQSM) scheme demonstrates promising modulation candidate for next generation vehicular networks with superior bit error rate performance.
