Generalized Spatial Modulation in Large-Scale Multiuser MIMO Systems
IEEE Transactions on Wireless Communications, 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 ...

Mutual Information Analysis for Generalized Spatial Modulation Systems With Multilevel Coding
IEEE Open Journal of the Communications Society, 2022 Generalized Spatial Modulation (GSM) enables a trade-off between very high spectral efficiencies and low hardware costs for massive MIMO systems. This is achieved by transmitting information via the selection of active antennas from a set of available ...
