A Survey on Spatial Modulation OFDM: Optimal Detection and Performance Analysis
ENP Engineering Science Journal, 2023 Spatial modulation is a novel modulation scheme that aims to acquire a trade-off between the two adverse purposes in wireless communications, namely the improvements of data rate and data reliability, by adjusting the operational transmit antenna index ...

A scalable performance–complexity tradeoff for constellation randomization in spatial modulation [PDF]
, 2016 It is widely recognised that traditional single RFchain aided spatial modulation (SM) does not offer any transmit diversity gain. As a remedy, constellation randomization (CR), relying on transmit pre-scaling (TPS), has been shown to provide transmit ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Low-Complexity Transmit Antenna Selection in Large-Scale Spatial Modulation Systems
International Journal of Antennas and Propagation, 2015 Transmit antenna selection (TAS) is an efficient way for improving the system performance of spatial modulation (SM) systems. However, in the case of large-scale multiple-input multiple-output (MIMO) configuration, the computational complexity of TAS in ...

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.
