“…According to the collected data, an environment model is established, and the user's requirements are analyzed and inferred [ 28 ]. There may be many levels involved in the model architecture in the process of modeling and speculation [ 29 ], which often requires a lot of calculation. And the models in different environments vary greatly.…”

“…There are several communication methods including energy detection [21], cloud computing [22], and frequency hopping [23]. Target tracking [24], network survivability [25], and resource management [26] can also be supported by the communication methods mentioned above. Using the Markov chain model, we are interested in the impact of weather on the path loss for SATCOM.…”

This paper investigates weather effects on a satellite communication (SATCOM) link communication channel model. Specifically, rain attenuation in the Ka band and X band of the SATCOM link for both uplink and downlink scenarios are presented. The weather model for the SATCOM link uses a Markov chain model with an average probability and transition probability for different states of weather, to investigate the impact of dynamic weather on the SATCOM link channel propagation model. Also, a power control method is proposed to achieve the required carrier to noise ratio in a SATCOM scenario using a Bayesian Network in Netica. The Bayesian Network models the space-ground link geometry and transmit power control to adapt to the dynamic weather. Simulations are implemented for the weather states during relatively long and short periods, path loss variations, and transmit power distributions over different scenarios. The simulation results demonstrate the effectiveness of the proposed weather model, Markov chain model, and the power control method for SATCOM.

Game theory is a useful method to model interactions between agents with conflicting interests. In this paper, we set up a Game Theoretic Model for Satellite Communications (SATCOM) to solve the interaction between the transmission pair (blue side) and the jammer (red side) to reach a Nash Equilibrium (NE). First, the IFT Game Application Model (iGAM) for SATCOM is formulated to improve the utility of the transmission pair while considering the interference from a jammer. Specifically, in our framework, the frame error rate performance of different modulation and coding schemes is used in the game theoretic solution. Next, the game theoretic analysis shows that the transmission pair can choose the optimal waveform and power given the received power from the jammer. We also describe how the jammer chooses the optimal power given the waveform and power allocation from the transmission pair. Finally, simulations are implemented for the iGAM and the simulation results show the effectiveness of the SATCOM power allocation, waveform selection scheme, and jamming mitigation.
