A new approach to blind multiuser detection based on intersymbol correlation

This work presents a simple and new blind multiuser detection technique that exploits the temporal cross correlation matrix of the received signal. The technique is useful for the two ISI scenarios, namely, a less severe ISI (one symbol interference case) and a more severe case that involves two symbol interference. We employ the cross-correlation matrix derived from the respective MMSE and decorrelating detectors. Computer experiments are conducted to justify the theoretical claims.
