Low-Complexity Transmit Antenna Selection in Large-Scale Spatial Modulation Systems

Low-Complexity Transmit Antenna Selection in Large-Scale Spatial Modulation Systems

Transmit antenna selection (TAS) is an efficient way for improving the system performance of spatial modulation (SM) systems. However, in the case of large-scale multiple-input multiple-output (MIMO) configuration, the computational complexity of TAS in large-scale SM will be extremely high, which p...
