Interference calculation results
Interference calculation results appear after the run of the ICE and provide evaluation of the probability of interference for the given scenario and for the given combination of interference calculation criteria (type of signal considered, C/I or other interference criterion, etc).
To access the interference calculation results, press on the Interference Calculations tab in the bottom part of the display. If more than one interference calculation was done (i.e. with different combination of interference criterion), the user may scroll through all of them by using the Previous/Next? buttons.
For each configuration the user will see:
- Calculation mode: compatibility / translation
- iRSS vector(-s) taken into account (blocking, unwanted, intermod)
- Translation parameters
- Interference calculation results:
- single interference probability value (compatiblity mode)
- probability as function of the translation parameter (translation mode)
