Transmitter Preprocessing Aided Spatial Modulation for Multiple-Input Multiple-Output Systems
, 2011 This paper proposes and studies a transmitter preprocessing aided spatial modulation (PSM) scheme, which conveys information jointly by a conventional amplitude-phase modulation (APM) and a preprocessing aided space shift keying (pre-SSK) modulation.

Low-complexity signal detection for generalized spatial modulation
, 2014 Generalized spatial modulation (GSM), in which only part of the transmit antennas are activated in each time slot, was recently proposed as a trade-off between spatial modulation (SM) and vertical Bell laboratories space-time (V-BLAST).

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 ...

Spatial Modulation and Generalized Spatial Modulation for Dynamic Metasurface Antennas
IEEE Transactions on Wireless CommunicationsTo address the significant capital expenditures (CAPEX) and operating expenses (OPEX) associated with each antenna having its dedicated radio frequency (RF) chain in multiple-input multiple-output configuration, various techniques have been introduced, such as analog architectures, hybrid architectures, and index modulation (IM).
