Abstract :
A singular values and singular vectors blind multiuser detector is proposed in this paper. This detector uses singular values and singular vectors of signal subspace to get a linear MMSE multiuser detector for a DS-CDMA system. This method uses FAST (fast approximate subspace tracking) algorithm to estimate singular values and singular vectors. The multiuser detector proposed in this paper can converge quickly and its output can achieve high SNR
