	abstract = {In this paper, we present an over-the-air (OTA) performance
analysis of Grassmannian signaling strategies in an orthogonal frequencydivision
multiplexing (OFDM) single-user multiple-input multiple-output
(SU-MIMO) scenario. Specically, we compare the Grassmannian signaling
technique to the dierential Alamouti scheme and a novel space-time
non-coherent scheme recently proposed in the context of 5G. As a performance
benchmark we include in the comparison the coherent Alamouti
scheme. We study the practical impairments associated to frequency
synchronization mismatches (frequency osets), as well as the eects of
time-varying channels for dierent spectral eciencies. The experimental
results show that non-coherent techniques are more robust to the
aforementioned impairments than the coherent Alamouti approach, while
Grassmannian methods are close to the dierential Alamouti scheme with
2 transmit antennas.},
