Receivers for nonlinearly separable scenarios inDS-CDMA

Receiver structures which overcome the nonlinear separation problem in a DS-CDMA system are presented. They are based on linear programming and the radial basis function. When a bank of matched filters is applied for preprocessing, the received DS-CDMA sequence is, under certain circumstances, no longer linearly separable.
