Blind Near-MAP Selection Diversity With Multiuser Detection for Multiuser OFDM [PDF]
IEEE Signal Processing Letters, 2006 This letter proposes a receiver algorithm for orthogonal frequency division multiplexing (OFDM) with receiver diversity that uses a new multiuser generalization of the maximum a posteriori probability (MAP) selection diversity combining followed by successive interference cancellation with least-square projection for multiuser detection.

A Low-Complexity Blind Multiuser Receiver for Long-Code CDMA
EURASIP Journal on Wireless Communications and Networking, 2004 Receivers for long-code systems are for computational reasons usually based on simple matched-filter techniques, and hence suffer from multiaccess interference.

Adaptive interference suppression for DS-CDMA systems based on interpolated FIR filters with adaptive interpolators in multipath channels [PDF]
, 2007 In this work we propose an adaptive linear receiver structure based on interpolated finite impulse response (FIR) filters with adaptive interpolators for direct sequence code division multiple access (DS-CDMA) systems in multipath channels.

Blind Multiuser Detection for Long-Code CDMA Systems with Transmission-Induced Cyclostationarity
EURASIP Journal on Wireless Communications and Networking, 2005 We consider blind channel identification and signal separation in long-code CDMA systems. First, by modeling the received signals as cyclostationary processes with modulation-induced cyclostationarity, long-code CDMA system is characterized using a time ...

Semi-blind and group-blind multiuser detection for the MC-CDMA uplink [PDF]
2004 IEEE 59th Vehicular Technology Conference. VTC 2004-Spring (IEEE Cat. No.04CH37514), 2005 In this contribution both semi-blind and group-blind multiuser detectors designed for uplink MC-CDMA systems are investigated in conjunction with different spreading codes. In the investigated scenario Walsh codes are shown to outperform both Gold codes and Zadoff-Chu codes.

Subspace blind adaptive detection for multiuser CDMA [PDF]
IEEE Transactions on Communications, 2000 Direct adaptive realizations of the linear minimum mean-square error (MMSE) receiver for direct-sequence code-division multiple access possess the attractive feature of not requiring any explicit information of interference parameters such as timing, amplitudes, or spreading sequences; however, they need a training sequence for the desired user ...

Simultaneous Principal-Component Extraction with Application to Adaptive Blind Multiuser Detection
EURASIP Journal on Advances in Signal Processing, 2002 SIPEX-G is a fast-converging, robust, gradient-based PCA algorithm that has been recently proposed by the authors. Its superior performance in synthetic and real data compared with its benchmark counterparts makes it a viable alternative in applications

Equalization with oversampling in multiuser CDMA systems [PDF]
, 2004 Some of the major challenges in the design of new-generation wireless mobile systems are the suppression of multiuser interference (MUI) and inter-symbol interference (ISI) within a single user created by the multipath propagation. Both of these problems
