Abstract

We deal with the problem of linear multiuser detection for asynchronous DS/CDMA systems. We introduce a new mean-output-energy cost function, whose constrained minimization leads to two new linear multiuser detectors, exploiting the information contained in the pseudo-autocorrelation of the observables, and which generalize and outperform the classical decorrelating and minimum mean square error receivers
