Abstract

"MéTODO E EQUIPAMENTO PARA TRANSMITIR A MENSAGEM DO CANAL DE SINCRONIZAçãO EM UM SISTEMA DE COMUNICAçãO POR MúLTIPLAS PORTADORAS". Um método e um equipamento para a transmissão de informações em broadcast em um sistema de comunicação por múltiplas portadoras. O canal de sincronização do sistema de múltiplas portadoras é transmitido com uma largura de banda de canal de 1,25 MHz ( isto é, através de uma única portadora ), e para especificar os canais preferidos para a transmissão do canal de sincronização em lugar dos canais preferidos para todo o sistema de múltiplas portadoras. A mensagem do canal de sincronização portará a informação adicional para indicar a freq³ência central de um sistema de múltiplas portadoras dentro de um conjunto reservado de bandas de freq³ências e indicar a freq³ência de um sistema de portadora única no conjunto reservado de bandas de freq³ências. Considerando novamente o bloco A da banda PCS, os canais preferidos para a transmissão do canal de sincronização podem ser selecionados como os canais 75, 150 e 225. Tal seleção assegura que um dos canais preferidos será sempre usado por qualquer sistema de múltiplas portadoras independentemente da localização de seu canal central.
