CA 2365126

A communication device comprising a turbo encoder (1) for performing a turbo- encoding on the lower two bits of transmission data to thereby output 2-bit information bits and 2-bit redundancy bits having a uniform error correction capability for each information bit, turbo decoders (first decoder (11), second decoder (15), etc.) for performing a soft judging on the lower two bits of a reception signal likely to be deteriorated in characteristics and performing an error correction by means of a Reed-Solomon code to thereby estimate the lower two-bit information bits, and a third judging unit (22) for performing a hard judging on the other bits in the reception signal to thereby estimate the other higher bits.

Cet appareil de communication comporte un turbo codeur (1) ex~cutant un turbo-codage sur les deux bits de poids faible de donn~es de transmission afin de sortir des bits d'information 2-bits de sortie et des bits de redondance 2-bits, chaque bit d'information ayant une capacit~ uniforme de correction d'erreur. L'appareil comporte ~galement des turbo d~codeurs (premier d~codeur (11), second d~codeur (15), etc.) proc~dant ~ une estimation approximative des deux bits de poids faible d'un signal de r~ception dont les caract~ristiques sont susceptibles d'Útre d~t~rior~es et r~alisant une correction d'erreur au moyen d'un code Reed-Solomon afin d'estimer les bits d'information de poids faible 2-bits. Cet appareil est, en outre, pourvu d'une troisi­me unit~ d'estimation (22) proc~dant ~ une estimation rigoureuse des autres bits du signal de r~ception afin d'estimer les autres bits de poids ~lev~.
