Abstract

"ARQ HìBRIDA ADAPTATIVA UTILIZANDO A ESTRUTURA DE CóDIGO TURBO". Uma estrutura genérica de ARQ Hibrido utilizando códigos Turbo é fornecida que requer a função de: a) codificação de canal, b) seleção de redundância, c) memória provisória e combinação de diversidade de proporção máxima, d) decodificação de canal, e) detecção de erro e f) enviar de volta uma confirmação ao transmissor. As funções (a) e (b) são efetuadas no transmissor enquanto as funções (c) a (f) são efetuadas no receptor. A velocidade de código inicial pode ser comunicada explicitamente ao receptor ou detectada cegamente.
