Abstract
"TRANSMISSãO E RECEPçãO EM MULTICANAL COM CODIFICAçãO EM BLOCOS EM UM SISTEMA DE COMUNICAçãO". Técnicas de transmissão e recepção de múltiplos canais com codificação em blocos em um sistema de comunicação são descritas. Em um aspecto, um canal de broadcast secundário (320) é transmitido simultaneamente com a informação de paridade, codificada a partir de um canal de broadcast primário (310) . Em outro aspecto, uma estação móvel (106) redireciona seu conjunto de circuitos de recebimento para receber uma ou mais partes do canal de broadcast secundário depois que uma parte suficiente do canal de broadcast primário é recebida sem erro identificado. Em outro aspecto, os canais de broadcast secundários associados com uma pluralidade de canais de broadcast primários (610) são multiplexados em um único canal secundário (620) . Vários outros aspectos também são apresentados. Esses aspectos apresentam o benefício de minimizarem os recursos de estação móvel necessários para se receber múltiplos canais de broadcast, além de reduzir a complexidade e os recursos de canal necessários para se transmitir múltiplos canais de broadcast.
