Constant modulus algorithm for blind multiuser detection

Proceedings of ISSSTA'95 International Symposium on Spread Spectrum Techniques and Applications, 2002
We propose the use of the constant modulus algorithm (CMA) for blind adaptive interference suppression in code division multiple access (CDMA) systems. Synchronous multiple access signals are considered, for simplicity. The convergence behavior of the CMA is analyzed to examine the conditions for lock onto the desired signal.

Blind Multiuser Detection Based on Kernel Approximation

2006
A kernel based multiuser detection (MUD) scheme in code-division multiple-access (CDMA) system is proposed. In this scheme, the support vector (SV) under support vector (SVM) framework is obtained through a kernel sparsity approximation, which regulates the kernel width parameter via a heuristic approach to obtain an approximate equivalent SV.

Asymptotic Analysis of Blind Multiuser Detection with Blind Channel Estimation

IEEE Transactions on Signal Processing, 2004
The analytical performance of the subspace-based blind linear minimum mean-square error (MMSE) multiuser detection algorithm in general multipath multi-antenna code-division multiple-access (CDMA) systems is investigated. In blind multiuser detection, the linear MMSE detector of a given user is estimated from the received signals, based on the ...

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 ...
