Abstract

This correspondence proposes a novel design strategy for linear multiuser detection in CDMA systems to satisfy a deterministic worst-case error performance measure. Formulations with and without the use of training signals are considered, and a near-far resistant solution for each is presented. Further, computationally efficient adaptive algorithms are derived in this framework that allow for sharing of detectors among different users
