Complex Quadrature Spatial Modulation
ETRI Journal, 2017 In this paper, we propose a spatial modulation (SM) scheme referred to as complex quadrature SM (CQSM). In contrast to quadrature SM (QSM), CQSM transmits two complex signal constellation symbols on the real and quadrature spatial dimensions at each ...

Joint Design of the Spatial and of the Classic Symbol Alphabet Improves Single-RF Spatial Modulation
IEEE Access, 2016 A new joint spatial and classic symbol alphabet is designed for spatial modulation (SM)-based multiple-input multiple-output systems. The employment of multiple active antennas instead of a single active antenna is proposed for increasing the achievable ...
