Double generalized spatial modulation
Transactions on Emerging Telecommunications Technologies, 2021AbstractIn this article, motivated by the enhanced spatial modulation and quadrature spatial modulation (QSM) systems, we proposed a new design of double generalized spatial modulation (DGSM), which further exploits the spatial domain not only for the transmission of more extra information bits by increasing the number of antenna index (AI) vectors in ...

Generalized Spatial Modulation With Multi-Index Modulation
IEEE Communications Letters, 2020In this letter, we propose a novel scheme extending index dimension with two distinct signal constellations, named as generalized spatial modulation with multi-index modulation (GSM-MIM). Through this scheme, which exploits the spatial domain and index domain, more extra information bits are transmitted by the spatial indexes as compared with the ...

Golden codeword‐based generalized spatial modulation
International Journal of Communication Systems, 2022SummaryConventional‐generalized spatial modulation (C‐GSM) is an multiple‐input multiple‐output (MIMO) spatial modulation (SM) scheme that transmits the same complex amplitude/phase modulation symbol from multiple active transmit antennas. By using two active transmit antennas during a transmission interval, C‐GSM is capable of achieving high ...

Generalized 3-D Spatial Scattering Modulation
IEEE Transactions on Wireless Communications, 2022Three-dimensional (3-D) massive multiple-input-and-multiple-output (MIMO) systems, which explore degrees of freedom in both the vertical and the horizontal dimensions, are a promising technology to enhance spectral efficiency in the next-generation communication systems.

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.

Distributed Generalized Spatial Modulation for Relay Networks
2020 28th Signal Processing and Communications Applications Conference (SIU), 2020A multi-relay cooperative diversity protocol based on the concept of Generalized Spatial Modulation (GSM) scheme is proposed in this paper, assuming that decode-and-forward relaying protocol is adopted at relays. This scheme is referred to as Distributed Generalized Spatial Modulation (DGSM) with activating more than one relay.

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.

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

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

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 ...
