The calculation of the interfering signal strength (iRSS) values for each event for unwanted interference (iRSSblocking) is as follows where the i-th interferer signal is defined as

 (Eq. 96)

The calculation is repeated for each defined interfering link so that the total iRSSblockingis

      (Eq. 97)


where for each interferer:

  • f_VLR: victim link operating frequency;
  • f_ILT: Interfering link operating frequency. Note that the trial of the dRSS frequency, fVLR, occurs only once for each simulation round, i.e. fVLR is trialled once, together with the VLT, VLR positions, the VLT transmit power and other distributions pertaining to the victim link. These values associated with the dRSS trial round then apply to all n trials of iRSS (where n is the number of interferers);
  •  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:.
  •  G_ILT->VLR: ILT antenna gain in the direction of the VLR;
  •  G_VLR->ILT: VLR antenna gain in the direction of the ILT;
  •  PL_ILT->VLR: path loss between the interfering link transmitter i and the victim link receiver;
  •  a_VLR(f_ILT - f_VLR): blocking attenuation of the victim link receiver, see ‎ANNEX 8:.´;
  •  MCL: Minimum coupling loss given by the system parameter definition.
