Objectives
The capacity in satellite networks is highly dependent on the efficient use of system resources and in particular the available frequency spectrum. Frequency reuse in multi-beam satellite networks allows significant increase in the system capacity but introduces interference.
Advanced interference mitigation techniques (IMT) allow the receiver to remove interference or detect additional useful information.
So far, preliminary simulation results showed promising enhancement in the system performance assuming ideal conditions.
The objective of this project is to analyse the enhancement in the system performance in a representative and realistic environment.
For this purpose a system demonstrator is developed that provides relevant subsystems and offers the interference mitigation techniques
Multi-User-Detection and Successive Interference Cancellation at the receiver.
Challenges
The challenge of this project is to create a realistic and representative test environment (taking into account system and payload characteristics) for multi-beam satellite systems with frequency re-use to analyse the enhancement in the system performance utilizing interference mitigation techniques.
System Architecture
The system demonstrator consists of the following modules:
- Bank of DVB-S2x transmitters
- Realistic satellite channel
- Receiver supporting IMTs
- Performance measurement unit
- Control & Monitoring GUI
Plan
The project is organized in two steps:
Step 1: Consolidation of the techniques and top-level demonstrator design
- MS1: Baseline Design Review (BDR)
- MS2: Preliminary Design Review (PDR)
Step2: Demonstrator development and performance validation
- MS3: Critical Design Review (CDR)
- MS4: Acceptance Review (AR)
- MS5: Final Review (FR)
- MS6: Final Presentation (FP)
Current Status
This project is successfully completed.
