Annotation of standard text IEC 61280-2-13-ed.1.0 :
IEC 61280-2-13:2024 series defines a procedure for calculating the root-mean-square error vector magnitude of optical n-APSK signals from a set of measured symbols. It specifically defines the normalization of the reference states and a procedure for optimal scaling of the measured symbol states. The procedure described in this document applies to single-polarized optical signals as well as to conventional polarization-multiplexed signals with independently modulated polarization tributaries. In general, it is not advisable to apply these procedures without modification to signals, in which optical amplitude, phase, and polarization state are simultaneously modulated to encode the information data. This document does not specify any signal processing steps for extracting the symbols from the received optical signals, because these steps depend on the optical receiver and can vary with the type of the transmitted n-APSK signal. These and optional additional signal processing steps are defined in application-specific documents. IEC 61280-2-13:2024 definit une procedure pour calculer la valeur efficace de lamplitude du vecteur derreur des signaux MDAP-n optiques a partir dun ensemble de symboles mesures. Elle definit specifiquement la normalisation des etats de reference ainsi quune procedure de mise a lechelle optimale des etats de symboles mesures. La procedure decrite dans le present document sapplique aux signaux optiques a polarisation unique ainsi quaux signaux multiplexes en polarisation conventionnels avec des tributaires de polarisation modules de facon independante. En general, il est deconseille dappliquer ces procedures sans modifier les signaux dans lesquels lamplitude optique, la phase et letat de polarisation sont simultanement modules pour coder les donnees. Le present document ne specifie aucune etape de traitement du signal permettant dextraire les symboles des signaux optiques recus, car ces etapes dependent du recepteur optique et peuvent varier selon le type du signal MDAP-n transmis. Ces etapes de traitement du signal ainsi des etapes supplementaires facultatives sont definies dans les documents specifiques a chaque application.
