What is it about?

The outage probability of spatial modulation (SM) multiple input multiple output (MIMO) systems incorporated with transmit antenna selection (TAS) over Rayleigh fading channels for binary phase shift keying signals is analysed. A closed form expression for the outage probability of the SM MIMO systems with TAS is derived and validated using the simulation results.

Why is it important?

The problem with SM MIMO systems is that the link of the antenna index used for communication may be completely down. This problem can be overcome if one selects S antennas out of Nt transmitting antennas with good links and applies SM on those S antennas.

Perspectives

First or second paper in the literature which implements spatial modulation with antenna selection.
