摘要
A blind adaptive optimisation criterion is proposed for use in the context of multiuser detection for SDMA systems. The proposed criterion combines an information-theoretic term with an explicit decorrelation procedure. Simulation results show that the proposed algorithm presents faster convergence than other existing blind multiuser criteria.
