Calculation of interfering signals iRSS_blocking and iRSS_unwanted

This page describes the flow of calculating one sample of the interfering signal strength (iRSS) values in a particular snapshot for unwanted interference (iRSS_unwanted) and for blocking interference (iRSS_blocking). The calculation is repeated for each defined interfering link:

• Trial of random parameters of the Interfering Transmitter (IT):
  • power supplied:
  • frequency: f_it;
  • antenna height: h_it;

• Trial of random parameters of the Wanted Receiver (WR):
  • antenna height : h_wr;
• Calculation of relative location for the given IT and WR pair;
• Calculation of azimuth and elevations angles for the given IT-WR path;
• Calculation of antenna gains for the given IT-WR path;
• If Power Control option was selected in the IT scenario settings:
  • Calculation of propagation path loss for IT-WR path;
  • Calculation of power control gain for the given IT-WR path;
• Calculation of relative location of the given IT with regards to VR;
• Calculation of azimuth and elevations angles for the given IT-VR path;
• Calculation of antenna gains for IT and VR antennas on the IT-VR path;
• Calculation of propagation path loss for the given IT-VR path;
• Calculation of VR blocking attenuation for blocking interference type:

• Calculation of total IT (unwanted) emissions level falling into VR bandwidth:

• Calculation of iRSS_unwanted according to the following formula:

• Calculation of iRSS_blocking according to the following formula:
