Abstract: The performance of two blind subspace-based multiuser detection is compared.One of them uses BISVD(Bi-Iteration SVD Subspace Tracking Algorithms)subspace tracking method, he other uses PROTEUS(Plane ROTation-based Evd-Updating Scheme)method.Simulations show that the two algorithms converge faster and have better performances, so they are good multiuser detection.

Key words: CDMA, multiuser detection, subspace tracking, blind adaptation
