SEAMCAT calculates the interfering signal resulting from the possible interfering system(s) at the interfering frequency as follows:

For each events{

If (dRSS > sensitivity){

Case 1: single source of interference

(Eq. 108)

where:

P^output_ILT: power supplied to the ILT antenna (before power control);
g^PC_ILT: power control gain for the ILT with the power control function, see ‎ANNEX 14;
PL_ILT->VLR: path loss between the interfering link transmitter i and the victim link receiver;
G_ILT->VLR: ILT antenna gain in the direction of the VLR;
G_VLR->ILT: VLR antenna gain in the direction of the ILT;
MCL: Minimum coupling loss given by the system parameter definition;
Rx_filter: Filtering of the receiver (if any).

Note: The filtering of the receiver is by default 0 dB (similarly to the default blocking filtering value).

Case 2: multiple source of interference

2.1 If the interferers are operating at the same frequency, iRSS_overloading is sum of each of the iRSS_overloading calculated for each of the source of interference.

2.2 If the interferers are operating at different frequencies, an iRSS_overloading should be calculated considering all of the sources of interference for each frequency (i.e. the sum of the iRSS overloading is performed at the specific frequency). Each of the calculated iRSS_overloading should be compared with the different overloading threshold extracted from the overloading mask depending on the considered frequency offset.
