Abstract

"APARELHOS E MéTODOS DE TRANSMISSãO E DE RECEPçãO DE INFORMAçãO". Um processo de decodificação de alto desempenho permitindo que o grau de liberdade de projeto seja substancialmente aumentado foi implementado. Um aparelho de transmissão (10) de um sistema de transmissão de dados e recepção compreende conversores (11~ 0~), (11~ 1~) e (11~ 2~), multiplicadores (12~ 0~), (12~ 1~) e (12~ 2~), somadores (13~ 0~) e (13~ 1~) e uma unidade de transmissão (14). Os conversores (11~ 0~), (11~ 1~) e(11~ 2~) convertem as sequencias de bit de informação b^ (0)^, b^ (1)^ e b^ (2)^ respectivamente nas seq³ências codificadas X^ (0)^, X^ (1)^ e X^ (2)^. Os multiplicadores (12~ 0~), (12~ 1~) e (12~ 2~) multiplicam respectivamente as seq³ências codificadas X^ (0)^, X^ (1)^ e X^ (2)^ pelas constantes a^ (0)^, a^ (1)^ e a^ (2)^. O somador (13~ 0~) adiciona uma seq³ência codificada de tempos constantes a^ (0)^ X^ (0)^ produzida pelo multiplicador (12~ 0~) como um resultado da multiplicação por uma seq³ência codificada de tempos constantes a^ (1)^ X^ (1)^ produzida pelo multiplicador (12~ 1~) como um resultado da multiplicação. O somador (13~ 1~) adiciona uma seq³ência codificada aditiva a^ (0)^ X^ (0)^ + a^ (1)^ X^ (1)^ produzida pelo somador (13~ 0~) como um resultado da adição, por uma seq³ência codificada de tempos constantes a^ (2)^ X^ (2)^ produzida pelo multiplicador (12~ 2~) como um resultado da multiplicação. A unidade de transmissão (14) transmite uma seq³ência codificada aditiva g (= a^ (0)^ X^ (0)^ + a^ (1)^ X^ (1)^ + a^ (2)^ X^ (2)^) produzida pelo somador (13~ 1~) como um resultado da adição a um aparelho externo como um sinal transmitido g'.
