Abstract

APARELHOS, SISTEMAS E MéTODOS PARA PRODUZIR SìMBOLOS COERENTES EM UMA REDE DE FREQüêNCIA úNICA. A presente invenção refere-se a um sistema, método, aparelho e código de computador que são proporcionados para produzir simbolos coerentes de transmissores digitais de RF. Um multiplexador recebe um sinal digital contendo dados de conteúdo a serem difundidos dos transmissores digitais de RF e insere um primeiro pacote de inicialização no sinal digital, onde a posição implícita dos pacotes de inicialização no sinal digital assinalarão quadros de dados nos transmissores digitais de RF. Onde o pacote de inicialização contém bytes de enchimento para inicializar deterministicamente codificadores de Trellis nos transmissores digitais de RF. Um emissor de fluxo de transporte transmite o sinal digital para a pluralidade de transmissores digitais de RF.
