Blind Space-Time Multiuser Detection Based on Subspace Tracking
Xiaoping Zeng · Transactions of Beijing Institute of Technology · 2010
Blind space-time multiuser detection using a subspace method for synchronous multipath antenna arrays CDMA systems is presented.Fast and stable yet another subspace tracker (FSYAST)is used for adaptive signal-subspace estimation,and the Kalman-type algorithm is employed for adaptive channel estimation of the synchronous multipath antenna array system.Simulation results show that,the proposed space-time MMSE detector has a better performance than other multiuser based on subspace tracking.
