Simulation Results
The simulation results of SEAMCAT consist of the following data sets when the victim is a generic system (i.e. non-CDMA / non-OFDMA):
| Event generation results: desired and undesired signal vectors and some associated data (notably the simulation radiuses), produced by the EGE during the event generation phase | Interference calculation results: probability of interference results calculated by the ICE |
 | 
|
When the victim is either a CDMA system or a OFDMA system, the results are as follow:
| CDMA modelling results: Impact of interference measured by excess outage which is the capacity loss (number of dropped mobile users) due to interference. | OFDMA modelling results: Impact of interference measured by bitrate loss due to interference |
