Verfahren nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass es Störsignale verwendet, die auf durch die befreundeten Empfänger bekannte Weise die für die befreundeten Sender und Empfänger nützlichen Informationen codieren, um diese über die verwendete Störstrategie, die Merkmale der Störwellenformen und der dazugehörigen Parameter, Sendeleistung, Antennendiagramm und -ausrichtung, Position, Höhe zu informieren, um die gemeinsame Optimierung der Sendungen und der Bearbeitungen im Empfang der nützlichen Übertragungen auf Höhe der befreundeten Sende- und Empfangsplattformen zu erleichtern, wobei die codierten Informationen durch die Analyse der durch die befreundeten Empfänger empfangenen Störsignale rekonstruiert oder in den durch die befreundeten Empfänger empfangenen Störsignale decodiert werden.
  5. Verfahren nach Anspruch 1, 2 oder 3, dadurch gekennzeichnet, dass es befreundete programmierbare Sender und Empfänger verwendet, welche geeignet sind, um dynamisch Sendebefehle in Bezug auf die Leistung und/oder zeitliche Parameter, die Wellenform, die räumlich-zeitlichen Codierungen, die Amplitudenphasen-Gewichtung der Antennenelemente zu berücksichtigen.
  6. Verwendung des Verfahrens nach einem der Ansprüche 1 bis 5 in Übertragungsnetzwerken, welche die Protokolle MIMO, MISO, SIMO oder SISO mit oder ohne Rücksendekanal der befreundeten Empfänger an die befreundeten Sender verwenden.
  7. Verwendung des Verfahrens nach einem der Ansprüche 1 bis 5 in einem Funknetzwerk, welches Empfänger umfasst, welche geeignet sind, um Werte von Übertragungskanälen an den nützlichen Sendern und an den Störvorrichtungen zu messen.
  8. Verwendung des Verfahrens nach einem der Ansprüche 1 bis 5 in einem Funknetzwerk, welches eine oder mehrere Empfangsstationen umfasst, welche Antennenelemente umfassen, welche mit einer Abfangvorrichtung gekoppelt sind, welche geeignet ist, um Messungen des Übertragungskanals an den nützlichen Sendern und an den Störvorrichtungen vorzunehmen.
