Extended Signed Quadrature Spatial Modulation System With Multi-User Support
(Institute of Electrical and Electronics Engineers (IEEE), 2021-04-01)
Signed quadrature spatial modulation (SQSM) was recently introduced to enhance the throughput of spatial modulation (SM) in multiple-input multiple-output (MIMO) systems. This strategy involves independently transmitting ...
A Study of Low Complexity Antenna Selection Algorithms for Signed Quadrature Spatial Modulation
(IEEE, 2020-12)
Transmit antenna selection (TAS) is a practical method to improve the bit-error-rate (BER) performance of
a multiple-input multiple-output (MIMO) systems. TAS is of particulate importance when spatial modulation (SM) is ...
Signed Quadrature Spatial Modulation for MIMO Systems
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Quadrature spatial modulation (QSM) was recently
proposed to increase the spectral efficiency of spatial modulation.
In QSM, the real and imaginary parts of a symbol are transmitted
independently from different antennas. ...
Super-orthogonal double space-time trellis code
(Elsevier BV, 2020)
This study develops a new class of super-orthogonal trellis codes for four transmit antennas based on double space-time codes. The transmit antennas are divided into two groups, each having two transmit antennas. The ...
