      This paper proposes a prediction method compatible with fast simulations to evaluate the performance of the Digital Video Broadcasting-Satellite Handled physical layer in terms of the Packet Error Rate, Erroneous Second Ratio, and zapping time. This method is based on the computation of the mutual information.

      The macroscopic selection diversity scheme selects the satellite with the maximum elevation angle among the visible satellites as being capable of providing the best quality link for signal propagation. To evaluate the performance of this scheme, we developed the PDF of the maximum elevation angles from an earth station to each visible satellite. The model has the advantage of not involving orbital simulations for data collection, thus avoiding statistical processing as well as curve fitting.

      Many of the limitations using AMC are due to the long round trip delay of a satellite system. This paper proposes an efficient AMC scheme with power control and symbol interleaving that can be effectively applied to LTE based satellite systems. The performance of proposed schemes is validated by the simulations.
