Abstract

"PROCESSOS PARA DECODIFICAR, PARA COMUNICAR E PARA TRANSMITIR INFORMAçãO, E, PROCESSO PARA COMUNICAR COM UM PRIMEIRO USUáRIO E UM SEGUNDO USUáRIO DESIGNADOS A UM MESMO CANAL DE ENLACE DESCENDENTE EM UM SISTEMA DE RADIOCOMUNICAçãO". Um sistema de radiocomunicação suporta multiplexação de multi-usuário. Comunicações de dados de meia taxa com intercalação de dados entre duas fontes são descritas. A técnica de multiplexação provê, efetivamente, dois subcanais de informação, que por sua vez provê uma oportunidade para melhora decodificação/demodulação de cada subcanal recodificando/remodulando informação depois de ecodificação/demodulação bem sucedida de um subcanal.
