Abstract

The relative error-probability performance of three linear multiuser detectors-the minimum mean-square error detector, the decorrelator, and the conventional matched filter (MF) detector-is investigated under nonorthogonal signaling and additive white Gaussian noise conditions. It is shown that, contrary to the general belief, the minimum mean-square-error (MMSE) detector does not uniformly outperform the other two detectors. In fact, even for the two-user case, one can find counterexamples where the matched filter is significantly better.
