Layered spatial modulation [PDF]
EURASIP Journal on Wireless Communications and Networking, 2018 In this paper, we propose a layered spatial modulation (L-SM) scheme that combines a multi-layered coding scheme with the spatial modulation. At each antenna selection, the number of active transmit antennas equals the number of layers. The proposed L-SM

IEEE Access, 2016 In this paper, we propose a virtual spatial modulation (VSM) scheme that performs index modulation on the virtual parallel channels resulting from the singular value decomposition of the multi-input-multi-output channels.

Optical spatial modulation design. [PDF]
Philos Trans A Math Phys Eng Sci, 2020 Visible light communication (VLC) systems are inherently signal-to-noise ratio (SNR) limited due to link budget constraints. One favourable method to overcome this limitation is to focus on the pre-log factors of the channel capacity. Multiple-input multiple-output (MIMO) techniques are therefore a promising avenue of research.

Spatial Terahertz Modulator [PDF]
Scientific Reports, 2013 Terahertz (THz) technology is a developing and promising candidate for biological imaging, security inspection and communications, due to the low photon energy, the high transparency and the broad band properties of the THz radiation1,2,3. However, a major encountered bottleneck is lack of efficient devices to manipulate the THz wave, especially to ...

Labeling Diversity for Media-Based Space-Time Block Coded Spatial Modulation
IEEE Access, 2020 Media-based space-time block coded spatial modulation (MBSTBC-SM) combines the advantages of media-based modulation (MBM) and STBC-SM. Meanwhile, labelling diversity (LD) has been applied to STBC-SM and improve the error performance.

Low complexity detection algorithm applied to spatial modulation system
Dianzi Jishu Yingyong, 2019 The paper proposes a low-complexity detection algorithm for spatial modulation. The proposed algorithm reduces the total complexity by reordering the receiving antennas. The algorithm combines the existing A-Star algorithm to layer and sort the receiving

Optimum GSSK Transmission in Massive MIMO Systems Using the Box-LASSO Decoder
IEEE Access, 2022 We propose in this work to employ the Box-LASSO, a variation of the popular LASSO method, as a low-complexity decoder in a massive multiple-input multiple-output (MIMO) wireless communication system.
