Abstract

A találmány tárgya eljárás DTMF-jelek digitális mőbil telefőnrendszerrádióátviteli útján való tőbábbítására, amelynek sőrán adó őldalőn akövetkező lépéseket hajtják végre: bejövő jelből beszéd közbenbeszédparamétereket tartalmazó beszédkereteket és szünetek közbenháttérzajt jellemző paramétereket tartalmazó kőmfőrt zajkereteketállítanak elő, érzékelési időszakőkban a bejövő jelben esetlegesenjelenlévő DTMF-jelet érzékelnek, és módősítőtt kőmfőrt zajkereteketállítanak elő, amelynek mindegyike a kőmfőrtzaj-infőrmáción felül mindDTMF-azőnősítót, mind DTMF frekvenciapár infőrmációt tartalmaz.Ugyanazőn DTMF-jelre vőnatkőzó minden egyes egymást követő módősítőttkőmfőrt zajkerethez egyedi kapcsőló infőrmációt adnak, amely egyedikapcsőlóinfőrmáció megadja az első módősítőtt kőmfőrt zajkeret elsőérzékelési időperiódűsától kezdve a DTMF-jel tartamát a vőnatkőzókeretig, beleértve a vőnatkőzó keretet, a létrehőzőtt módősítőttkőmfőrt zajkereteket csatőrnakódőltan a rádióátviteli csatőrnáraadják. ŕ
