Code division multiple access based on independent codes and turbo decoding

Abstract

L’article etudie un algorithme de codage/decodage pour l’acces multiple par etalement de spectre base sur un decodage iteratif (turbo). L’algorithme est applicable aux systemes synchrones et asynchrones. Les sequences pseudo-aleatoires quasi-orthogonales du systeme d’acces multiple par etalement de spectre a sequences directes sont remplacees par celles de codes correcteurs d’erreurs independants construits par combinaison de codes convolutifs et d’entrelaceurs aleatoires. Le brouillage est reconstruit au niveau du decodeur a l’aide d’une information de sortie souple. Les resultats des simulations montrent que le decodeur iteratif conjoint est capable d’eliminer completement le brouillage multiutili-sateur. Les performances du systeme d’acces multiple propose tendent pratiquement vers celles d’un systeme monoutilisateur.
