Pour améliorer la robustesse de la technique de modulation de polarisation (PM) appliquée dans les systèmes de satellites à double polarisation, une méthode de démodulation assistée par forçage nul (ZFAD) est proposée pour éliminer la dégradation de la PM due à l'effet de dépolarisation (DE). L'élimination DE dépend traditionnellement de la méthode de pré-compensation, qui est basée sur les informations sur l'état du canal (CSI). Or, la distance entre les partenaires de communication dans les systèmes satellitaires est si grande que le CSI ne peut pas toujours être mis à jour à temps du côté de l'émetteur. Par conséquent, les méthodes de pré-compensation risquent de ne pas fonctionner correctement. Dans la méthode ZFAD, le CSI est estimé côté récepteur et la matrice de forçage zéro est construite pour traiter le signal reçu avant de démoduler le signal PM. De cette façon, le DE est éliminé. De plus, nous dérivons l’expression du rapport signal/bruit reçu des méthodes PC et ZFAD avec le modèle de canal statistique pour une meilleure comparaison. Les résultats de l'analyse théorique et de la simulation démontrent que la méthode ZFAD peut éliminer efficacement l'effet DE et obtenir de meilleures performances en matière de taux d'erreur de symbole que la méthode de pré-compensation.

Abstract: To improve the robustness of the polarization modulation (PM) technique applied in dual-polarized satellite systems, a zero-forcing aided demodulation (ZFAD) method is proposed to eliminate the impairment to the PM from the depolarization effect (DE). The DE elimination is traditionally dependent on the pre-compensation method, which is based on the channel state information (CSI). While the distance between communication partners in satellite systems is so long that the CSI can not be always updated in time at the transmitter side. Therefore, the pre-compensation methods may not perform well. In the ZFAD method, the CSI is estimated at the receiver side and the zero forcing matrix is constructed to process the received signal before demodulating the PM signal. In this way, the DE is eliminated. In addition, we derive the received signal-to-noise ratio expression of the PC and ZFAD methods with the statistical channel model for a better comparison. Theoretical analysis and simulation results demonstrate the ZFAD method can eliminate the DE effect effectively and achieve a better symbol error rate performance than the pre-compensation method.
