Power delay profile (PDP) was investigated to give an overview of broadband channel model. Thereafter, a long delay caused by the obturation of tunnel is observed and investigated in all the scenarios. The measurements show that the reflection can be greatly remained by the tunnel,which leads to long delay cluster where the reflection, but direct ray, makes the main contribution for radio wave propagation. |
