Blind adaptive algorithms for minimum variance CDMA receivers.

Blind adaptive algorithms for minimum variance CDMA receivers.

Constrained optimization methods have received considerable attention as a means to derive blind multiuser receivers with low complexity. The receiver's output variance is minimized subject to appropriate constraints which depend on the multipath structure of the signal of interest. When multip...
