This paper presents an analysis of the Orthogonal
Time Frequency Space (OTFS) modulation scheme when applied
to realistic vehicular channel situations. OTFS modulates symbols
in delay-Doppler domain, hoping to exploit diversity in both. The
penalty for doing this is the requirement of complex interference
cancellation equalizers, as this domain incurs a strong amount
of intercarrier and intersymbol interference. We conduct this
analysis using measured millimeter wave vehicular channels,
and we assume typical physical layer settings for a performance
analysis. Our results show that there is a challenging trade-off
between channel conditions that are easy to equalize and channel
conditions that allow OFTS to exploit the two-dimensional
diversity. In the first case we observe a good overall performance
that is barely enhanced by employing OTFS. In the second case
performance gain through OTFS is visible, yet with a bad overall
performance.
