Systemc-AMS model of a dynamic large-scale satellite-based AIS-like network

In an automatic identification system (AIS), ground base stations can only provide services within a very limited range off the coast. Recent analyses show that low earth orbit (LEO) satellites can expand the service of AIS to a global range. Multi-antenna satellite receivers are suggested to be used to cancel the interference between messages in heavily trafficked areas. In this paper, we present a SystemC-AMS model for a dynamic large-scale satellite-based AIS-like network as the test environment for such algorithms. Complex data type is used in the signal flow. Many effects such as Doppler shifts, path loss, arrival angles, and the real-time transmission and collisions of messages are modeled. This model is further tested with a multi-user detection algorithm in the satellite receiver and validated with receivers in matlab.
