assumption that the maximum cell radii for microcells and macrocells are 200 and 500 m,<br />
respectively, and that the distribution of user terminals o<strong>ver</strong> the cell area is uniform. The median<br />
values are dependent on cell radii, thus the tabulated values are not uni<strong>ver</strong>sal in bad urban scenarios.<br />

4.5 CDL Models<br />
Although the clustered delay line (CDL) model is based on similar principles as the conventional<br />
tapped delay line model, it is different in the sense that the fading process for each tap is modelled in<br />
terms of a sum of sinusoids rather than by a single tap coefficient. The CDL model describes the<br />
propagation channel as being composed of a number of separate clusters with different delays. Each<br />
cluster, in turn, is composed ofa number of multipath components (rays) that have the same delay<br />
values but differ in angle-of-departure and angle-of-arrival. The angular spread within each cluster can<br />
be different at the BS and the MS. The offset angles represent the Laplacian PAS of each cluster. The<br />
a<strong>ver</strong>age power, mean AoA, mean AoD of clusters, angle-spread at BS and angle-spread at MS of each<br />
cluster in the CDL represent expected output of the stochastic model with parameters listed in Table<br />
4-8. Exceptions are the fixed feeder link models in scenario B5, for which no stochastic models have<br />
been defined.<br />
Parameter tables for the CDL models are given in Section 6 of this document.<br />
