On an efficient equalization structure for aeronautical communications via a satellite link
Résumé
In this paper, we investigate a sub-optimal but efficient receiver structure for the equalization of aeronautical communications via a satellite link. The structure is based on the inherent sparsity of the equivalent discrete baseband channel model that enables an efficient implementation based on simple parallel trellis using Maximum A Posteriori (MAP) detection combined with iterative residual interference estimation and cancellation. The proposed scheme is shown to be very efficient while significantly decreasing the complexity compared to a MAP receiver that does not exploit the sparsity of the aeronautical channel.
