Abstract
In this letter, the idea of transmit antenna selection is combined with the offset spatial modulation (OSM) technique. Specifically, two novel transmit antenna selection schemes, termed as antenna selection based on grouped Euclidean distance (AS-GED) and channel coefficient (AS-CC), are developed toward a flexible tradeoff between system performance and computational complexity. Simulation results show that the proposed antenna selection schemes achieve significant performance improvement compared to traditional OSM systems.
