System Link Group

This type of Link allows Links of groups to be associated and the calculation of statistics across the group to be defined in various ways.

One application of this kind of Link Group is to look at the effects of diversity on the performance of a single hop system.

To create a System Link Group click ‘add’ in the Link Group List (accessible via the Model menu or via the Link Group icon in the toolbar). Then select the first option – System Link Group.

A new Link Group, default name System Link Group will appear in the Link Group list.

Double click on the Link Group or click the Edit button to edit the Link Group.

The edit dialog has three tabs:

  1. The Links Tab – add and remove Links from the Link group here.
  2. The Advanced tab – override simulation defaults for statistics collection and Link graphical display characteristics here.
  3. The Calculation tab – define how statistics over the whole group are calculated.

The first two tabs are the same as for the Created Empty Link Group: the System Link Group has in addition the “Calculation” tab.

The Calculation Tab is where you tell the software how to deal with the calculations across multiple links at each time step
