Abstract

Um das Schätzen von drahtlosen Übertragungskanälen in Telekommunikationssystemen zu verbessern, zu vereinfachen und zu optimieren, werden die Korrelationen von unterschiedlichen Kanalimpulsantworten auf unterschiedliche Weise ausgenutzt. Beispielsweise wird eine von zwei Nachrichten, die für einen anderen Sender/Empfänger bestimmt ist, für die Kanalschätzung benutzt. Zusätzlich oder alternativ wird die Differenz zwischen zwei Kanalimpulsantworten bestimmt. Wenn diese Differenz einen vorgegebenen Grenzwert unterschreitet: dann wird eine mittlere Kanalimpulsantwort gebildet; und/oder dann werden in jeden zweiten Burst Trainingsinformationssequenzen bzw. Testsignale nicht übertragen. Zusätzlich oder alternativ könnte die Korrelation der zwei Kanalimpulsantworten mittels 'LOOK-UP'-Tabellen zur Schätzung der Geschwindigkeit eines Teilnehmers benutzt werden.
