This option corresponds to duplicate n times a specific interfering links on a circle or on a hexagonal grid as illustrated below in (a) and (b) respectively. It is available by clicking on (Image Added). These interferers have the same characteristics as the reference interfering link. It has the purpose of automatically generating a regular pattern of interfering links.

The multiple generate feature graphical interface consists of 3 parts:

• Selection of the reference interferer
• Relative position of this reference interferer to the victim link
• Layout preview of the new interferers

...

(a) Selection of the reference interferer

You can choose an interfering link that will be used to clone the new interferers.

Figure 217215: Selection of the reference interferers

In the Generate Multiple Interfering Link dialog box, when selecting ok, 6 new interferers will now be present in the workspace, centered to the selected interferer (i.e. interfering link 1).

(b) Relative position of this reference interferer to the victim link

You can adjust the position of the interferers with respect to either the VLT (Victim link transmitter) or the VLR (Victim link receiver). When the generate multiple feature is run the relative positioning of interfering link mode (i.e. in the victim receiver to interfering transmitter path tab) is by default overwritten. In this case the center of the interferers is set to (1,1) to VLT.

(d) Illustrative example of the generation of multiple interfering link

...

During the multiple link generation, the intersite distance parameter (0.433 km in the example), in combination with the specified initial offset angle, will overwrite the original coordinates (Delta X/Delta YDeltaY) in the Vr‐It path tab setting of the Interfering links.
