Abstract :
This paper describes the channel models that are being used within the DVB-S2X standardization effort to define the next generation air interface for satellite broadcast systems. These channel models have been selected in order to represent the most common on-board and on-ground equipment characteristics as well as system configurations. The channel linear and non-linear distortions are described in details and their effects to the end-to-end performance characterized in terms of the resulting carrier-to-interference ratio. The channel propagation contributions affecting the overall link C/I (cross-polar) is also described. Finally, a model allowing to assess the performance of advanced adjacent satellite interference cancellation techniques is also introduced. The models described in this paper are also currently being used to fully characterize the performance of the DVB-S2x specifications for the preparation of the Guidelines document.
