Linear multiuser detectors for synchronous codedivision multipleaccess channels
 IEEE TRANS. INFORM. THEORY
, 1989
"... In codedivision multipleaccess systems, simultaneous multiuser accessing of a common channel is made possible by assigning a signature waveform to each user. Knowledge of these waveforms enables the receiver to demodulate the data streams of each user, upon observation of the sum of the transmitt ..."

. It is shown that in the synchronous case the performance achieved by linear multiuser detectors (whose complexity per demodulated bit is only linear in the number of users) is similar to that of optimum multiuser detection. Attention is focused on detectors whose linear memoryless transformation is a general
Robustness of DSCDMA multiuser detectors
 in Proc. IEEE Communication Theory MiniConference
, 1997
"... Abstract – The robustness against errors in the estimation of channel parameters such as time delay and phase is studied for different multiuser detectors in a directsequence codedivision multiple access system. Simulations indicate that most of the studied detectors perform well in a system with n ..."

Iterative Implementations for Linear Multiuser Detectors
, 1999
"... We consider the convergence properties of several iterative implementations of linear multiuser receivers, under the assumption of long random spreading sequences. We find that parallel interference cancellation diverges for systems loads of greater than 17%. Using known results from the theory of i ..."

Spectral efficiency of lowcomplexity multiuser detectors
 Proceedings of the IEEE International Symposium on Information Theory
, 2000
"... Abstract A family of multiuser detectors is analyzed which require neither matrix inversions nor other operations with significant complexity. The time complexity per bit of most of them is independent of the number of users. Nevertheless, their spectral efficiency for random spreading sequences ..."

Adaptive Power Control with MMSE Multiuser Detectors
, 1997
"... Power control algorithms assume that the receiver structure is fixed and iteratively update the transmit powers of the users to provide them with an acceptable quality of service while minimizing the total transmitter power. Multiuser detection on the other hand optimizes the receiver structure wit ..."

A Joint Performance Measure for the Decorrelating Multiuser Detector
"... Abstract  We analyze the performance of the decorrelating multiuser detector for a wireless communication system. Instead of looking at the error probability for each user, we focus on the probability distribution of the number of correctly decoded users at the receiver and the average number of co ..."
