where τ is the excess delay and b is a time constant. For the suburban LOS environment the constant b is
40 MHz.

5.4.7.5 Scenario D1
Power delay profiles for the rural environment were investigated in 2004 and <strong>report</strong>ed in [D5.3] for LOS
propagation conditions. In our current campaign both LOS and NLOS conditions were investigated. The
results of the current campaign are shown in the figure Figure 5.48. The results in [D5.3] are comparable,
but less detailed.
Mean PDP profiles at 100 MHz bandwidth and 5.25 GHz centre-frequency in a rural environment are
shown in the following figures.

Power delay profile for LOS conditions has been fitted to two segments with an exponential function
P
−bτ
( τ ) e
= (5.21)
where τ is the excess delay and b is the time-constant. Here the constants b 1 is 220 MHz for the first
segment and b 2 is 15.6 MHz for the second one.
For the D1 rural NLOS conditions the PDP has been investigated in the current measurement campaign.
The measured PDP can be seen in the Figure 5.49 below with dual slope and single slope fitting.
