Nonlinear group-blind multiuser detection.

A nonlinear group-blind technique is developed for joint detection of some given users' data in a CDMA uplink environment with the presence of unknown interference. This method performs the so-called ?slowest-descent search? over a likelihood function of the desired users, starting from the est...
