Claim One:
1. Method of detecting a plurality of symbols (d k (i)) transmitted by or for a plurality K of users, each symbol belonging to a modulation constellation and being the subject of a spectral spreading before being modulated on a plurality L of carriers, the said method comprising a step of demodulation ( 420 ) and a step of spectral despreading ( 430 ) of the received signal (r(i)) in order to supply a vector (y 2 (i), {tilde over (y)} 2 (i)) characteristic of the said signal, characterised in that it comprises a step ( 450 ) of searching, within an array of points (&Lgr; 2,&OHgr; 2 ) generated by the symbols of the said modulation constellations, for at least the closest neighbour of the said vector.
