Adaptive Multiuser Detection

Proceedings of IEEE 3rd International Symposium on Spread Spectrum Techniques and Applications (ISSSTA'94), 1995
An important thrust in research in multiuser detection is the design of adaptive detectors, which self-tune the detector parameters from the observation of the received waveform. The literature on this subject is surveyed in this tutorial paper.

Design Linear Multiuser Transmitters from Linear Multiuser Receivers

2007 IEEE International Conference on Communications, 2007
Novel concepts are introduced for finding the relationship between multiuser detection (MUD) and multiuser transmission (MUT), so that the study in MUT can benefit from the well-built theory in MUD. Our study shows that, for any given linear MUD scheme, there exists a counterpart linear MUT scheme, which can be readily designed from the original linear

Optimum Multiuser Asymptotic Efficiency

IEEE Transactions on Communications, 1986
The degradation in bit error rate due to the presence of multiple-access interference in a white Gaussian channel can be measured by the multiuser asymptotic efficiency, defined as the ratio between the SNR required to achieve the same uncoded bit error rate in the absence of interfering users and the actual SNR.

Asymptotic multiuser efficiency for decision-feedback multiuser detection

Proceedings of ICC/SUPERCOMM '96 - International Conference on Communications, 2002
In this work, arbitrarily tight upper and lower bounds to the asymptotic multiuser efficiency (AME) are derived for K asynchronous users and decision-feedback multiuser detection. Because the multiple-access interference is noncausal, the precursor interference may be canceled out by making tentative decisions via conventional or decorrelated decisions,
