In the [MET_99] Doppler power spectrums of two big hall measurements are presented in Figure 5.88<br />

<strong>and</strong> Figure 5.89. In the envir<strong>on</strong>ment named Novi3, MS was at the height 1.69 m <strong>and</strong> BS at the 2.34m<br />

height. At the Aalborg internati<strong>on</strong>al airport MS was at the height 1.69 m <strong>and</strong> BS at the 2.53m.<br />

In [LUI99] the results of the COST 259 are presented. Big hall envir<strong>on</strong>ment is named General<br />

Factory/Hall (GFH). Length, width <strong>and</strong> height are 90, 30 <strong>and</strong> 10 m respectively. BS height was 8 m <strong>and</strong><br />

MS height was 1.5 m.<br />

Probability of LOS was 0.5. Narrowb<strong>and</strong> path-loss exp<strong>on</strong>ent was found to be 2.2. Inter cluster delay<br />

spread is 360 ns. Mean XPR is 6 dB. XPR spread is 6 dB.<br />

5.5.3 Scenario B5<br />

Note also that for the feeder scenarios we do not have any data <strong>and</strong> therefore the modelling is based<br />

entirely <strong>on</strong> the literature study. Secti<strong>on</strong> 5.5.3.1 below addresses the Doppler spectrum for fixed<br />

applicati<strong>on</strong>s, while Secti<strong>on</strong> 5.5.3.2 <strong>and</strong> 5.5.3.3 reviews publicati<strong>on</strong>s <strong>on</strong> basic parameters for the “rooftop<br />

to rooftop” <strong>and</strong> “street <strong>level</strong>” to “street-<strong>level</strong>” scenarios.<br />

5.5.3.1 Doppler for stati<strong>on</strong>ary scenarios<br />

In comm<strong>on</strong> for the feeder scenarios studied here is the assumpti<strong>on</strong> that the positi<strong>on</strong> of the transmitter <strong>and</strong><br />

receiver are fixed. In mobile-communicati<strong>on</strong>s temporal variati<strong>on</strong>s are modelled by using a moving<br />

transmitter travel through an envir<strong>on</strong>ment of fixed scatterers. In fixed applicati<strong>on</strong>s the temporal variati<strong>on</strong>s<br />

are induced by the movements of the scatterers. In [TPE02] a theoretical model is built where the change<br />

of phase of scatter between time t <strong>and</strong> t+?t is given by<br />
