Abstract

"SINTONIZADOR MULTICANAL DE CANCELAMENTO DE VALOR INDESEJáVEL BASEADO EM TRANSFORMAçãO". Um receptor de satélite inclui um sintonizador de cancelamento de sinal para processar uma pluralidade de diferentes sinais de transponder para prover simultaneamente uma pluralidade de diferentes fluxos de bits. O sintonizador de cancelamento de sinal inclui (a) um demultiplexador para demultiplexar um sinal recebido representando a pluralidade de sinais de transponder em um número de sinais decimados, cada sinal de transponder transportando um fluxo de bits, e (b) um elemento de transformação operativo no número de sinais decimados para prover pelo menos dois dos fluxos de bits simultaneamente.
