Equalisation method for a downlink channel in a telecommunication system transmitting MC-CDMA symbols on a plurality of carrier frequencies, in which a plurality of links are established between a transmitter and a plurality of receivers in order to transmit a plurality of coded signals, each link using a distinct access code amongst N possible codes, the method providing that, for at least one receiver, a vector (Y) representing the components of the signal received by the receiver on the different carrier frequencies is subjected to a filtering step adapted for supplying an observable vector (Z, Z') and the said observable vector is used for effecting an estimation of the said transmitted symbols according to a mean square error minimisation criterion.
