| 摘要 |
The present invention concerns a method for detecting a plurality of symbols (dk(i)) transmitted by or for a plurality K of users, each symbol belonging to a modulation constellation, said method comprising a filtering step filtering a received signal for supplying a vector (z) each component of which being related to a user, said method further comprising a searching step for searching the closest neighbour of said vector among candidates belonging to a lattice of points generated by said modulation constellations, the search being limited to a volume centered around said vector and being carried out by sequentially selecting a coordinate (bk) of a candidate for each dimension of said vector. The components of said vector are reordered according to an ordering rule prior to said search. <IMAGE>
