Title (EN) ADAPTIVE POLARIZATION ARRAY (APA)
(FR) RÉSEAU DE POLARISATION ADAPTABLE (APA)
Abstract:
(EN) An Adaptive Polarization Array (APA) Algorithm is described for adjusting the polarization orientation of antennas, such as Dual-polarized array antennas. The APA Algorithm searches to find a polarization state that maximizes a signal quality of a received signal in the presence of interfering signals and noise. The search facilitates adjustment of a polarization state of, for example, receive antennas to maximize a signal quality metric. A proxy metric having no local maxima other than the global maximum is used to search the polarization search domain to find a best polarization state.
(FR) L'algorithme de réseau de polarisation adaptable (algorithme d'APA) ci-décrit permet d'ajuster l'orientation de la polarisation des antennes, par exemple des antennes réseaux à double polarisation. Ledit algorithme d'APA recherche un état de polarisation qui maximise la qualité de signal d'un signal reçu en présence de signaux de brouillage et de bruit. La recherche facilite l'ajustement de l'état de polarisation des antennes de réception, par exemple, afin de maximiser une mesure de qualité de signal. Une mesure de substitution qui n'a pas d'autres maximums locaux que le maximum global sert à rechercher le domaine de recherche de polarisation afin de trouver un meilleur état de polarisation.
