Abstract

Method for ordering a number K of given users in a digital signal equalizing and decoding device receiving the signals from the K users comprising at least the following steps: a step in which the K users, or at least the majority of K users, are ordered according to a defined criterion for a user k taking account of the power of user k corrected for intersymbol interference associated with this user k and with other users, and an equalizing and decoding step. Use of the method in a CDMA context.
