Requirement

This emulation framework is using the LoRaMatlab library that we developed.

https://www.mathworks.com/matlabcentral/fileexchange/81166-loramatlab

How to use?

1. Open the "SatelliteOnDutyCalculation.m" to obtain the on-duty table of satellites with respect to the local observer.

2. Users can change the constellation parameter {N, inc, P, F, h, WalkerDelta in [True, False]}

3. Users can also change the satellite antenna beamwidth (beamwidth) to alter the coverage of satellites to limit the number of avaliable satellites.

4. Open "TheEmulator_Case#.m" to emulate the LoRa-over-Satellite communication. Case 1: Random Access Case 2: Scheduled Access (when there is any avaliable satellite links) Case 3: Scheduled Access with Packet Reptition. Case 4: Round-Robin Scheduled Access (Interference-free) User can change the SF,

5. The NB-IoT-over-Satellite emulation script is also provided. It requires the MATLAB LTE toolbox to be pre-installed.

Output

Packet error rate: PER
