Signed Quadrature Spatial Modulation for MIMO Systems [PDF]
IEEE Transactions on Vehicular Technology, 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. A new spatial modulation technique, termed signed quadrature spatial modulation (SQSM), is introduced in this paper.

On the Capacity of Generalized Quadrature Spatial Modulation
IEEE Wireless Communications Letters, 2023 In this letter, the average mutual information (AMI) of generalized quadrature spatial modulation (GQSM) is first derived for continuous-input continuous-output channels. Our mathematical analysis shows that the calculation error induced by Monte Carlo integration increases exponentially with the signal-to-noise ratio.
