Energy Efficient Transmission over Space Shift Keying Modulated MIMO Channels [PDF]
, 2012 Energy-efficient communication using a class of spatial modulation (SM) that encodes the source information entirely in the antenna indices is considered in this paper. The energy-efficient modulation design is formulated as a convex optimization problem,

An Intelligent Target Feature Recognition Method Based on Multi-mode OAM Beams
Leida xuebao, 2021 Target detection based on space modulation requires a large number of test modes with space-time independence. The Orbital Angular Momentum (OAM) beams are orthogonal to each other and have infinite modes.
