| Abstract | Abstract : In the next-generation Transformational Satellite Communications System, one essential element is to provide satellite communication to on-the-move terminals, which suffer from intermittent channels due to blockages by objects in their environments. Presented is our approach for modeling these blockage channels for different environments, in order to allow accurate prediction of system behavior via numerical simulation or symbolic analysis. In particular, we focus on the scenario of link-layer ARQ (automatic repeat request) and the simple two-state Markov model is amenable to symbolic analysis, but is less accurate, while a more complex mixture model leads to better predictions, but can be studied only via numerical simulation. We also introduce a new memory-decay curve concept for the characterization of channel memory and the estimation of model parameters. |
