Abstract

"SISTEMA DE TRANSMISSãO POR RáDIO DIRETA DE SATéLITE COM FORMATAçãO DE DADOS DE TRANSMISSãO, PROCESSAMENTO POR CARGA úTIL DE SATéLITE E RECEPçãO POR RECEPTORES DE RáDIO REMOTOS" é fornecido um sistema de transmissão por rádio direta de satélite o qual monta bits de programas de transmissão em incrementos de taxa primária, vários dos quais são montados em um quadro. Os quadros são divididos em símbolos que são desmultiplexados em canais alternados de uma pluralidade de canais de taxa primária. Os canais de taxa primária são desmultiplexados sobre um número correspondente de freq³ências de transmissão para transmissão para um satélite. Um desmuliplexor polifásico a bordo separa sinais de transmissão de estação terrestre para satélite em fluxos de símbolos, multiplexados de divisão de tempo. Um desmodulador de modulação por comutação de fase a bordo desmodula os símbolos em dados de faixa de base digitais. O aparelho de alinhamento de taxa a bordo corrige diferenças de taxa de relógio entre um relógio a bordo e os símbolos de transmissão. A carga útil de satélite comuba os símbolos para fluxos de dados multiplexados de divisão de tempo (TDM) utilizando duas memórias intermediárias de pingue pongue e um comutador de encaminhar. Os receptores processam os fluxos de TDM utilizando preâmbulos de quadro mestre e canais de controle de ranhura de tempo fornecidos nos mesmos pelo satélite, e coletores de controle de serviço (SCHS) fornecidos no mesmo por estações de transmissão. Os SCHs fornecem endereçamento de receptores específicos e serviços de multimídia. Um sistema de gerenciamento é fornecido para gerenciar e controlar o satélite e estações de transmissão.
