Abstract
Patente de Invenção: <B>"PROCESSO E SISTEMA DE ESTAçãO RADIOBASE PARA A TRANSMISSãO DE VOZ ATRAVéS DE UMA INTERFACE DE RáDIO EM UM SISTEMA DE RADIOCOMUNICAçõES DIGITAL"<D>. é indicado um processo e um sistema de radiobase para a transmissão de voz através de uma interface de rádio em um sistema de radiocomunicações digital. No processo de acordo com a invenção é transmitido pelo menos um sinal através de uma interface de rádio entre uma estação radiobase do sistema de estação radiobase e uma estação de rádio. Deste sinal é determinado pelo menos um valor característico sobre condições de transmissão da interface de rádio. O valor característico é armazenado em pelo menos uma instalação de memória e é considerado em um instante mais tarde adicionalmente aos valores característicos atuais determinados, para uma codificação de voz e de canal do lado de emissão.
