Abstract

Patente de Invenção: "SISTEMA DE COMUNICAçãO INTERNA E SINCRONIZAçãO PARA UM RECEPTOR". Em um sistema de multiusuário para transmissão sem fio de sinais de vídeo, áudio e/ou combinados ou sinais de comunicação gerais, é dada uma proposta para o sincronismo e a sincronização das várias mensagens dos usuários. A proposta é baseada em uma técnica de transmissão e acesso de FDMA/TDMA. Os dados dos usuários são transmitidos em um quadro comum compreendendo um número de fendas de controle e também um número de fendas de dados, cada fenda estando associada a um tempo de proteção. Os sinais de fenda têm as características de i) a posição no tempo do primeiro sinal de fenda de controle no quadro ser baseada no último sinal de fenda de controle do quadro anterior, ii) a posição no tempo dos sinais de fenda de controle subseq³entemente transmitidos ser baseada na posição do sinal de fenda de controle anterior, iii) a posição no tempo dos sinais de fenda de dados ser baseada ou ser referida ao último sinal de fenda de controle no mesmo quadro, o qual pode ser um sinal de um outro usuário ou de seu próprio, iv) no final do quadro, atrás do último sinal de fenda, um tempo de proteção adicional ou aumentado significativamente mais longo do que os tempos de proteção gerais associados às outras fendas ser colocado. A proposta também inclui um sistema de comunicação e um receptor para um sistema de comunicação.
