This paper presents a very preliminary
comparison between the IEEE 802.11p channel model
parameters with parameters evaluated from new high
speedmeasurements in Lund, Sweden. Following interesting
differences as well as similarities are observed:
The measured maximum excess delay is about one fifth
of the one proposed in the IEEE 802.11p model. The
amplitude distribution for each tap can be approximated
as Ricean distribution, with a very high Rice factor
for the first tap and small Rice factors for later taps.
Similar to the IEEE 802.11p model we observe a strong
line of sight path near to the Doppler frequency of zero
and weaker paths at Doppler frequencies about twice
the measurement vehicle´s speed. As a key result we
show that the average delay-Doppler spectra, which is
one part of the tap delaymodel, does not reflect the time
variant behavior of the radio channel.
