Yanrong Zhang, Guoan Bi, Boon Poh Ng · Electronics Letters · 2000
A subspace training method is presented for multiuser detection in dispersive DS-CDMA channels with the presence of multiple access interference (MAI). By using a small number of training symbols of the desired user, the proposed method is computationally efficient and near-far resistant.
