Summary

[edit]
Description
Deutsch: Konstellationsdiagramme einiger der 6.817 OFDM Träger des DVB-T Signals (8k Modus, 16 QAM). Die Zahl im Hintergrund entspricht der Trägernummer k. Die Träger k=0 und k=618 beinhalten einen kontinuierlichen Pilotton (blaue Kreise), ferner werden in einzelnen OFDM Symbolen zwischen den Nutzdaten sogenannte verstreute Pilottöne übertragen (z.B. in k=3). Die Pilottöne werden mit erhöhter Sendeleistung übertragen. Zur Konfiguration des Empfängers wird redundant auf mehreren Trägern (z.B. k=209 und k=413) die Übertragungsparameter (Transmission Parameter Signalling - TPS) des Senders übertragen. Diese Information wird DBPSK moduliert (rote Kreise). (Konstellationsdiagramm aller OFDM Träger)
