Abstract
We consider the application of adaptive backoff margins to mobile satellite links. The mapping of channel state information to modulation and coding schemes is complemented by a margin which is obtained as the result of a stochastic gradient descent scheme which uses the decoding history reported by the receiver. The proposed solution does not rely on the knowledge of the channel model and its parameters, which helps to improve its robustness with respect to previous schemes. Analysis and simulations are provided to certify the potential of the exposed ideas.
