Extended quadrature spatial modulation for MIMO wireless communications

Physical Communication, 2019
Abstract This paper presents an extended quadrature spatial modulation (EQSM) scheme that combines K quadrature spatial modulation (QSM) constellations to achieve a K -fold spectral efficiency (SE) enhancement. The idea underlying EQSM consists in using the average powers of the K QSM constellations as an additional dimension for the

Improved Quadrature Spatial Modulation

2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017
Quadrature spatial modulation (QSM) exploits the in-phase and quadrature antenna dimensions to increase the number of spatial constellation points. In this paper, an improved version of QSM, which is naturally called improved quadrature spatial modulation (IQSM), is proposed.

Fully-Quadrature Spatial Modulation

2018 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2018
In this paper, a new multiple-input multiple-output (MIMO) modulation scheme termed as fully-quadrature spatial modulation (F-QSM) is proposed. The F-QSM is a class of space modulation techniques (SMTs) that harness the spatial positions of the transmit antennas in the transmit antenna array to fulfill high data rates.

Modified Generalised Quadrature Spatial Modulation

2019 National Conference on Communications (NCC), 2019
In this paper, we propose a Modified Generalised Quadrature Spatial Modulation (mGQSM) scheme with multiple RF chains. The proposed scheme, compared to GQSM, proposes a novel codebook design which provides one extra bit per channel use (bpcu) spectral efficiency with the constraint of $\{\log_{2}\begin{pmatrix} N_{t}\\ N_{r_{f}} \end{pmatrix}\}\geq0.5$

Trellis coded quadrature spatial modulation

Physical Communication, 2018
Abstract In this paper, a novel multiple-input multiple-output (MIMO) transmission scheme called trellis coded quadrature spatial modulation (TC-QSM), is proposed. In the proposed scheme, trellis coded modulation (TCM) principle is applied to the emerging quadrature spatial modulation (QSM) scheme, and a trellis encoder and a QSM mapper are jointly ...

Diversity-Achieving Quadrature Spatial Modulation

IEEE Transactions on Vehicular Technology, 2017
In this paper, motivated by the recent concept of quadrature spatial modulation (QSM), we propose a diversity-achieving QSM (DA-QSM) transmission scheme. In the proposed scheme, two sets of dispersion matrices are employed, and $P$ out of $Q$ dispersion matrices are activated in each set.

Constellation Design for Quadrature Spatial Modulation

2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017
This paper considers constellation design for quadrature spatial modulation (QSM) to minimize the average probability of error. Different than the constellation design previously obtained for spatial modulation (SM), it is shown that, the error performance of QSM not only depends on the Euclidean distances between the amplitude-phase modulation (APM ...

Spatial Diversity-Achieving Quadrature Spatial Modulation

2018 IEEE International Conference on Automation, Electronics and Electrical Engineering (AUTEEE), 2018
Quadrature space modulation (QSM) was viewed recently as a viable multiple-input multiple-output (MIMO) communication technique for next generation wireless system. In this paper, the new scheme achieving spatial diversity of QSM system called SDA-QSM is designed.
