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 ...

Generalized space-time shift keying designed for flexible diversity-, multiplexing- and complexity-tradeoffs [PDF]
, 2011 In this paper, motivated by the recent concept of Spatial Modulation (SM), we propose a novel Generalized Space-Time Shift Keying (G-STSK) architecture, which acts as a unified Multiple-Input Multiple-Output (MIMO) framework.
