Experimental Analysis of Spatial Modulation Systems in Mixed LOS/NLOS Scenarios
IEEE Access, 2022 Spatial modulation (SM) as a multiple-input multiple-output (MIMO) technique is a solution suitable which offers, with low system complexity and cost, improved spectral efficiency compared to single-input-single-output (SISO) systems.

Exploring symmetry in wireless propagation channels [PDF]
2017 European Conference on Networks and Communications (EuCNC), 2017 Wireless communications literature is very rich with empirical studies and measurement campaigns that study the nature of the wireless propagation channel. However, despite their undoubted usefulness, many of these studies have omitted a fundamental yet key feature of the physical signal propagation, that is, wireless propagation asymmetry.
