Codebook-based precoding for generalized spatial modulation with diversity
EURASIP Journal on Wireless Communications and Networking, 2019 This paper investigates codebook-based precoding for spatial modulation (SM) and generalized spatial modulation (GSM) systems. Codebook-based precoding allows the system to dispense with full channel state information at the transmitter (CSIT).

Reconfigurable Intelligent Surface Enabled Spatial Modulation for Visible Light Communications
IEEE Photonics Journal, 2023 An important issue in visible light communications (VLC) is how to boost up the system throughput even when the line-of-sight (LOS) link is blocked by obstacles. In this paper, we propose reconfigurable intelligent surface (RIS) based spatial modulation (

On the Capacity and Performance of Generalized Spatial Modulation
, 2015 Generalized spatial modulation (GSM) uses $N$ antenna elements but fewer radio frequency (RF) chains ($R$) at the transmitter. Spatial modulation and spatial multiplexing are special cases of GSM with $R=1$ and $R=N$, respectively.

Improved QRD-M Detection Algorithm for Generalized Spatial Modulation Scheme
International Journal of Antennas and Propagation, 2017 Generalized spatial modulation (GSM) is a spectral and energy efficient multiple-input multiple-output (MIMO) transmission scheme. It will lead to imperfect detection performance with relatively high computational complexity by directly applying the ...

Generalized Spatial Modulation in Indoor Wireless Visible Light Communication
, 2015 In this paper, we investigate the performance of generalized spatial modulation (GSM) in indoor wireless visible light communication (VLC) systems. GSM uses $N_t$ light emitting diodes (LED), but activates only $N_a$ of them at a given time.

Low-complexity Lattice Reduction Aided Detection for Generalised Spatial Modulation [PDF]
, 2016 Generalised spatial modulation (GSM) was first introduced with the maximum-likelihood (ML) optimum decoder. However, ML decoder may be infeasible for practical implementation due to its exponential complexity especially when the number of antennas or the

Generalized Spatial Modulation in Large-Scale Multiuser MIMO Systems
, 2015 Generalized spatial modulation (GSM) uses $n_t$ transmit antenna elements but fewer transmit radio frequency (RF) chains, $n_{rf}$. Spatial modulation (SM) and spatial multiplexing are special cases of GSM with $n_{rf}=1$ and $n_{rf}=n_t$, respectively ...
