Blind multiuser detection over multipath channels based on subspace tracking
Wu Qiang · Journal of the China Railway Society · 2001
In this paper, a blind multiuser receiver for frequency-selective fading channel based on subspace tracking has been presented. This receiver combines the consideration of multiuser detection and Rake receiver. Its performance is better than the D-rake receiver. It has property of low complexity and high performance. Its computation complexity depends only on the chosen subspace tracking method.
