Abstract

"MéTODO E SISTEMA PARA PROCESSAR UM QUADRO DE SINALIZAçãO AMR A SER TRANSMITIDO EM UM CANAL GERAN DE MEIA TAXA UTILIZANDO UM ESQUEMA DE MODULAçãO QUE TRANSPORTA N BITS EM UM SìMBOLO". A presente invenção relaciona à transferência dos quadros de sinalização nos canais de meia taxa GERAN (GSM/EDGE Radio Access Network/Rede de Acesso de Rádio GSM/EDGE) utilizando o esquema de modulação que transporta n bits em um símbolo. De forma a ser capaz de utilizar a codificação de canal existente desenvolvida para os canais com diferentes modulações e para evitar a taxa convolucional alta e os códigos do bloco, o quadro de sinalização AMR a ser transferido é codificado usando o procedimento de codificação definido para o canal de meia taxa GSM utilizando o esquema de modulação GMSK, o procedimento de codificação produzindo então um fluxo de saída codificado. Em resposta à codificação, cada bit de um fluxo de bit codificado é repetido n vezes, desse modo o fluxo de bit repetido é obtido, e os símbolos a serem transmitidos são formados do fluxo de bit repetido.
