Abstract

"DECODIFICADOR TURBO EFICIENTE EM TERMOS DE ESPAçO". Um decodificador turbo eficiente. O decodificador turbo revelado inclui um primeiro modo de funcionamento, no qual o decodificador turbo usa um primeiro loop funcional. O primeiro loop funcional inclui um banco de memória, um intercalador de leitura, um primeiro multiplexador (MUX), um arquivo de RAM, um decodificador log-MAP, um intercalador de leitura e um segundo MUX. O decodificador turbo revelado inclui também um segundo modo de funcionamento, no qual um segundo loop funcional é usado. O segundo loop funcional inclui o banco de memória, o primeiro MUX, o arquivo de RAM, o decodificador log-MAP e o segundo MUX. O banco de memória é uma memória extrínseca de porta dual. O circuito de decodificador turbo revelado é comutado entre o primeiro modo e o segundo modo.
