Hardware-Aware Quadrature Spatial Modulation

2022 30th Signal Processing and Communications Applications Conference (SIU), 2022
Spatial modulation (SM) is a simple multi-input multi-output (MIMO) communication technique in which a single transmit antenna is active for each symbol period. Quadrature spatial modulation (QSM), on the other hand, is a form of SM in which independent transmit antenna selection is made for the real and imaginary parts of the symbols.

Quadrature Spatial Scattering Modulation for mmWave Transmission

IEEE Communications Letters, 2023
In this letter, we investigate a novel quadrature spatial scattering modulation (QSSM) transmission technique based on millimeter wave (mmWave) systems, in which the transmitter generates two orthogonal beams targeting candidate scatterers in the channel to carry the real and imaginary parts of the conventional signal, respectively.
