Abstract

"PROCESSOS E DISPOSITIVOS DE TRATAMENTO PARA A EMISSãO DE SìMBOLOS DE INFORMAçãO SOBRE OS CANAIS MULTIPLEXADOS, E DE TRATAMENTO CORRESPONDENTE PARA A RECEPçãO". Um diagrama para multiplexar o canal de transporte em um ou vários canais de comunicação é adaptado para operar em um modo normal e um modo comprimido, deste modo requerendo uma taxa de símbolo mais confiável, na qual períodos inativos são previstos em canais de comunicação. Com o intuito de adaptar taxas em cada um dos canais de transporte, os símbolos são estampados em dois diferentes tempos: os símbolos marcados são inicialmente introduzidos, os quais submetem-se a várias etapas de processamento, particularmente intercalar com outros bits de informação ante de serem excluídos da seq³ência de transmissão. As etapas de processamento podem ser similarmente transportadas no modo normal e no modo comprimido, os quais limitam a existência de complexidade na comunicação.
