A typical scenario consists of one victim link which describes the communication system being interfered and at least one interfering link which describes the interfering system(s) that may cause interference to the victim link. CDMA or OFDMA systems are modeled differently, using special algorithm that creates a grid of multiple cells.
Set the scenario by selecting what system will be the victim and what system will be the interferer. Remember that setting the frequency at the “scenario level” overwrite any settings at the “System level”.

You can also pre-defined the dRSS distribution that you want. When the User-defined dRSS (dBm) is selected, you have to set the value of wanted signal (dRSS) through the associated data entry field. In this case it overrides the dRSS calculation and will substitute the dRSS values by the results of trialling the user-defined dRSS distribution data. This way of defining dRSS is often used e.g. when victim link is deliberately set to operate at or close to victim link receiver's sensitivity threshold, etc.
Table 38: Simulation scenario – Victim System
Description | Symbol | Type | Unit | Comments |
Frequency | fVLT or fILT | D or S | MHz | Distribution of the centre frequency of the victim system or the interfering system links. |
User defined dRSS:
| dRSS | D or S (if constant) | dBm/VLR reception bandwidth. | If User-defined dRSS is checked, you then define a distribution of the desired Received Signal Strength. See ANNEX 4: for further details. |
The simulation control is explained in Section 2.10.
