Interference criteria | C/I C/(N+I) (N+I)/N I/N | SScalar | dB | You can define at At least one of these criteria .should be defined: ( C/I, C/(N+I), (N+I)/N, I/N). one of these criteria is chosen for each interference probability calculation. |
Calculate interference criteria | - | calculator | - | This feature allows you to evaluate the evaluation of the consistency between the entered interference criteria ( C/I, C/(N+I), (N+I)/N, I/N) and proposes alternative solution values that you can selectcan be selected to ensure consistency between them. |
The “calculate interference criteria” is a user friendly calculator for the interference criteria. It avoids conspicuous calculations,
...
increases the transparency and
...
avoids consistency check warnings because of the use of inconsistent sets of
...
values.
The calculation and selection of a consistent set of interference criteria is implemented. The calculator opens with the existing values in the interference criteria fields of the workspace. A checkbox (default: ON) allows to force the consistency of the C/(N+I) value with the workspace, i.e. the values ‘Noise floor’ and ‘Sensitivity’. The relation between the values is given in the formula C/(N+I) [dB] = Sensitivity [dBm] – Noise floor [dBm]
The Interference Criteria Calculator displays all possible sets of consistent interference criteria rounded to
...
two decimals. The same set is displayed only once. As a consequence of rounding, the displayed sets are differ at least 0.
...
01 dB in one of the four values.
When you select the column of values you want and click ok, the values are copy/pasted to the “Interference criteria” panel.
