Abstract

"PROCESSOS PARA DEMODULAR UM SINAL DE COMUNICAçãO E PARA COMUNICAR COM UM TERMINAL DE USUáRIO". é fornecido um processo de demodular um sinal de comunicação. O sinal de comunicação inclui uma pluralidade de páginas com cada página tendo uma pluralidade de endereços e pacotes de dados correspondentes. O processo de demodulação inclui as etapas de receber o sinal de comunicação em um terminal de usuário, identificar quais da pluralidade de páginas são destinadas ao terminal de usuário receptor, e identificar quais da pluralidade de pacotes de dados dentro da página identificada são destinados para o terminal de usuário receptor, e demodular somente os pacotes de dados identificados como sendo destinados para o terminal de usuário receptor.
