Trellis Coded Generalized Spatial Modulation
2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014In this paper, a novel trellis coded generalized spatial modulation (TCGSM) scheme is presented and analyzed. Similar to that of the traditional generalized spatial modulation (GSM), a subset of the entire transmit antennas is selected for transmission at each time slot.

High-rate generalized spatial modulation
2016 24th Signal Processing and Communication Application Conference (SIU), 2016In this study, a new high-rate generalized spatial modulation scheme is proposed for multiple-input multiple-output (MIMO) communications systems. In this scheme, two modulated symbols and the indices of the active two transmit antennas which are used in the transmission of these symbols are determined according to the incoming data bits.

Signal-Spatial Constellation Optimization for Generalized Spatial Modulation
2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014This paper considers the optimal constellation design for the generalized spatial modulation (GSM). The signal and spatial parts of the constellation are jointly designed where the signal part is not restricted to the conventional amplitude/phase modulation constellation points. The design problem is formulated as an optimization problem where a set of

Trellis coded generalized spatial modulation with spatial multiplexing
2017 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), 2017In this paper, a trellis-coded generalized spatial modulation scheme with spatial multiplexing is presented to achieve higher spectral efficiency. A joint detector for information bits in the spatial domain and constellation domain is also designed. Both the advantages of the Viterbi algorithm for detecting trellis-coded information bits and the sphere

Generalized Multistream Spatial Modulation Based on Frequency-Phase Modulated Signals
IEEE Wireless Communications Letters, 2022In this letter, we present an approach to building a new generalized multistream spatial modulation system (GMSM), where the information is conveyed by the two active antennas with signal indices and using all possible active antenna combinations. The signal constellations associated with these antennas may have different sizes.

Dynamic spatial modulation for next generation networks
Physical Communication, 2019Abstract A major challenge for fifth generation (5G) wireless communication, which is expected to be deployed around 2020 is to provide 10 times higher spectral efficiency and energy efficiency than fourth generation (4G). Spatial modulation (SM) is a novel multiple input and multiple output (MIMO) technique, which provides an exceptional trade-off ...

Novel detection schemes for generalized quadrature spatial modulation
International Journal of Communication Systems, 2021SummarySpatial Modulation (SM) is a technology that incorporates digital modulation and coding with multiple antennas to achieve high data rates along with improved energy efficiency. Quadrature spatial modulation (QSM), which extends the transmitted signals to in‐phase and quadrature domains, has recently been proposed to improve spectral efficiency ...

On generalized spatial modulation for multiuser wireless communications
2017 14th IEEE Annual Consumer Communications & Networking Conference (CCNC), 2017The recently proposed multiple-input multiple-output (MIMO) technique of spatial modulation (SM) has attracted a good deal of attention due to its low implementation and computational complexity, and the spectral efficiency and energy efficiency gains it offers over many conventional MIMO schemes.

Integer-Forcing Detection of Generalized Spatial Modulation
2018Generalized spatial modulation (GSM) activates more transmit antennas than spatial modulation to increase the spectral efficiency. Although the maximum likelihood (ML) detector is able to achieve the optimal performance, its exhaustive search leads to intractable computational complexity.

Performance Analysis and Optimization of Secure Generalized Spatial Modulation
IEEE Transactions on Communications, 2020Artificial noise (AN) is considered as a new physical layer technology to improve the security of wireless systems. In this paper, we investigate secure transmission of AN-aided generalized spatial modulation (GSM), which maintains the same hardware requirements at the transmitter as the conventional GSM.
