4.2.1 Generation of bad urban channels (B2, C3)<br />

Bad urban channel realizations can be created as modified B1 and C2 NLOS procedures as follows:<br />

Step 1:<br />

Drop five far scatterers within a hexagonal cell, within radius [FSmin, FSmax]. For FSmin and FSmax<br />

values see Table 4-3. For each mobile user determine the closest two far scatteres, which are then used for<br />

calculating far scatterer cluster parameters.<br />
