Abstract

Cette invention se rapporte à des procédés servant à attribuer des codes d'étalement à des connexions de liaison aval avec des débits binaires variables dans des systèmes de communication DS-CDMA. A une première connexion est attribué un premier nombre de codes (x) pris dans un premier ensemble (S1) de codes orthogonaux. A une seconde connexion est attribué un second nombre de codes (y). Une première partie (y-k¿1?) du second nombre de codes (y) est prélevée dans le premier ensemble (S1) de codes orthogonaux. Une seconde partie (k¿1?) du second nombre de codes (y) est prélevée dans un second ensemble (S2) de codes orthogonaux, qui n'est pas orthogonal par rapport au premier ensemble (S1).
