Abstract

Zum Übertragen von Datenströmen über Kanäle mit jeweils mehreren Ein- und Ausgängen werden die Datenströme (d[n]) an den Kanal-Eingängen jeweils in vorgegebener Weise zu Sendesignalen (s[n]) moduliert, und es werden an den Kanal-Ausgängen aus den Empfangssignalen (x[n]) durch Entzerrung entsprechende Datenströme (d[n]) hergeleitet; dabei wird an den Kanal-Eingängen den Datenströmen (d[n]) eine vorgegebene Matrixmodulations-Struktur (Mk) aufgezwungen und an den Kanal-Ausgängen die Entzerrung der Empfangssignale (x[n]) auf Basis dieser bekannten vorgegebenen Matrixmodulation durchgeführt.
