Abstract

Abstract: A blind multiuser detector based on linear transform and prediction for CDMA systems is proposed. It can eliminate MAI and ISI simultaneously. Using only the spreading sequences of the desired user, we first process the received signals by linear prediction. Next, MMSE detectors are obtained without explicit channel estimation. This avoids any channel estimation error, and the resulting method is more accurate.

Key words: MMSE, CDMA, blind multiuser detection, linear transform
