Energy Efficient Transmission over Space Shift Keying Modulated MIMO Channels [PDF]
, 2012 Energy-efficient communication using a class of spatial modulation (SM) that encodes the source information entirely in the antenna indices is considered in this paper. The energy-efficient modulation design is formulated as a convex optimization problem,

IEEE Access, 2019 Focusing on the issue that the spatial modulation (SM)-aided full-duplex relaying (SM-FDR) scheme cannot obtain transmit diversity, we present a space-time block coded spatial modulation-based full-duplex relaying (STBC-SM FDR) protocol in this paper. In

Labeling Diversity for Media-Based Space-Time Block Coded Spatial Modulation
IEEE Access, 2020 Media-based space-time block coded spatial modulation (MBSTBC-SM) combines the advantages of media-based modulation (MBM) and STBC-SM. Meanwhile, labelling diversity (LD) has been applied to STBC-SM and improve the error performance.

Complex Quadrature Spatial Modulation
ETRI Journal, 2017 In this paper, we propose a spatial modulation (SM) scheme referred to as complex quadrature SM (CQSM). In contrast to quadrature SM (QSM), CQSM transmits two complex signal constellation symbols on the real and quadrature spatial dimensions at each ...

Joint Design of the Spatial and of the Classic Symbol Alphabet Improves Single-RF Spatial Modulation
IEEE Access, 2016 A new joint spatial and classic symbol alphabet is designed for spatial modulation (SM)-based multiple-input multiple-output systems. The employment of multiple active antennas instead of a single active antenna is proposed for increasing the achievable ...

International Journal of Engineering and Advanced Technology, 2019 In this paper, we analyze the performance of spatially modulated (SM) multiple input multiple output (MIMO) system and spatially modulated MIMO cooperative system with multiple relays employing selective decode and forward (SDF) protocol. Here the analysis is done for pre-determined orthogonal channel for SM MIMO and SM MIMO cooperative system using M ...

An Effective Spatial Modulation Based Scheme for Indoor VLC Systems
IEEE Photonics Journal, 2022 We propose an enhanced spatial modulation (SM)-based scheme for indoor visible light communication systems. This scheme enhances the achievable throughput of conventional SM schemes by transmitting higher order complex modulation symbol, which is ...
