Blind multiuser detection: a subspace approach

IEEE Transactions on Information Theory, 1998
Summary: 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 ...

Blind adaptive multiuser detection

IEEE Transactions on Information Theory, 1995
This paper introduces an adaptive multiuser detector which converges (for any initialization) to the minimum mean-square error detector without requiring training sequences. This blind multiuser detector requires no more knowledge than does the conventional single-user receiver: the desired user's signature waveform and its timing.

Blind multiuser detection via interference identification

IEEE Transactions on Communications, 2002
Previous results on blind multiuser detection apply in situations where the signal parameters of the users of interest are known, and those of the interferers; are unknown. In this paper, we consider the new paradigm of an N-user system, in which K users are active, and the problem is to detect G users of interest out of those K active users when the ...

Group-blind multiuser detection for uplink CDMA

IEEE Journal on Selected Areas in Communications, 1999
Previously developed blind techniques for multiuser detection in code division multiple access (CDMA) systems lead to several near-far resistant adaptive receivers for demodulating a given user's data with the prior knowledge of only the spreading sequence of that user.

Blind Multiuser Detection Based on Tikhonov Regularization

IEEE Communications Letters, 2011
In code-division multiple-access (CDMA) system, ill-conditioning of the covariance matrix of the received signal may degrade the performance of minimum mean-squared error (MMSE) detector, especially when signal-to-noise ratio (SNR) is high and small data sets are available for covariance matrix estimation.

Adaptive transmitter optimization for blind and group-blind multiuser detection

IEEE Transactions on Signal Processing, 2003
The linear subspace-based blind and group-blind multiuser detectors recently developed represent a robust and efficient adaptive multiuser detection technique for code-division multiple-access (CDMA) systems. In this paper, we consider adaptive transmitter optimization strategies for CDMA systems operating in fading multipath environments in which ...
