Simulation Results
The simulation results consist of two kinds of data sets:
- 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
- CDMA modelling: Impact of interference measured by excess outage (capacity loss due to interference)
- OFDMA modelling: Impact of interference measured by bitrate loss due to interference
