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.

Energy efficiency of multiuser detection
WCNC. 1999 IEEE Wireless Communications and Networking Conference (Cat. No.99TH8466), 2003We study the power consumption of several multiuser detectors in the power controlled DS-CDMA system. The matched-filter detector, linear MMSE detector, successive interference cancellation (SIC), and LMMSE-SIC are considered. Closed form analysis and numerical results show that by using a multiuser detector, system power consumption can significantly ...

Multiuser Detection via Compressive Sensing
IEEE Communications Letters, 2012In this paper, we consider a multiuser detection technique when the signal sparsity is changing over time. The key ingredient of our method is a clever switching between the CS reconstruction algorithm and classical detection depending on the sparsity level of the signals being detected. Since none of these approaches is uniformly better in a situation

Precoded opportunistic multiuser detection
2012 IEEE International Conference on Communication Systems (ICCS), 2012In this paper, we study multi-user multi-input-multi-output (MU-MIMO) wireless system for spectrum sharing over a limited bandwidth, in which transmit covariance matrices of the coexisting users independently updated in an iterative manner for individual rate maximization.

Multiuser Activity and Data Detection via Sparsity-Blind Greedy Recovery for Uplink Grant-Free NOMA
IEEE Communications Letters, 2019Exploiting the sparse activity of users, compressed sensing (CS) has been of interest in multiuser detection (MUD) for non-orthogonal multiple access (NOMA), to enable a massive connection of users in machine-type communications (MTC). In this letter, we

Conference Record of Thirty-Second Asilomar Conference on Signals, Systems and Computers (Cat. No.98CH36284), 2002
An iterative receiver structure is proposed for decoding multiuser information data in a convolutionally coded DS-CDMA system. The receiver performs two successive soft-output decisions, achieved by a soft-input soft-output (SISO) multiuser detector and a bank of single-user SISO channel decoders, through an iterative process.

Blind multiuser detection: a subspace approach
IEEE Transactions on Information Theory, 1998Summary: A new multiuser detection scheme based on signal subspace estimation is proposed. It is shown that under this scheme, both the decorrelating detector and the linear minimum mean-square-error (MMSE) detector can be obtained blindly, i.e., they can be estimated from the received signal with the prior knowledge of only the signature waveform and ...

Belief Propagation for Coded Multiuser Detection
2006 IEEE International Symposium on Information Theory, 2006In this paper a simplified parallel belief propagation (BP) algorithm is suggested as a suboptimal soft-input soft-output multiuser detector in an iterative multiuser decoding scheme. The iterative decoding scheme itself is based on applying an outer BP algorithm for message passing between the BP multiuser detector and the single-user decoders.

Multiuser detection in impulsive channels
Annales Des Télécommunications, 1999L’article etudie la detection de donnees dans les systemes d’acces multiple par repartition en code utilisant la methode de sequence directe, en presence de bruit ambiant non gaussien. Ce probleme intervient dans des situations pratiques puisque de nombreux canaux physiques sur lesquels on emploie des communications a acces multiple sont notoirement ...
