Assured satellite communications: A minimal-cost-variance system controller paradigm
Khanh Pham · 2016
This paper begins to bridge theoretical systems control with satellite communications in fundamental ways. In view of satellite system controllers, quality of service of user terminals needs a radically different perspective to reliably maintain a minimum adaptive link margin to account for link state uncertainties. Special emphasis is therefore given to the cost-variance, discrete-time control theory which enables an effective design for reliability to analyze the behavior of Signal-to-Interference-Plus-Noise Ratio (SINR)-based tracking systems. The work further articulates the use of state estimates for terminal power adjustments supported by discrete Kalman filtering with intermittent blockages. Moreover, the recent assessment of multi-access interference protection recommends that terminal powers should continue to be subject to terminal power control output back-off constraints. Lastly, communication rates for terminal reports from active remote terminals to the satellite ground hub can be optimized by means of the model-based triggering events.
