Subspace-Based Blind and Group-Blind Space-Time Multiuser Detection for the Generalized Multicarrier DS-CDMA Uplink

, 2006
Subspace-based blind and group-blind space-time multiuser detection is invoked for a smart antenna aided generalized MC DS-CDMA system communicating over a dispersive Space-Time (ST) Rayleigh fading channel, where the channel estimates are attained by ...

Low Complexity Receiver Structures for Space-Time Coded Multiple-Access Systems

EURASIP Journal on Advances in Signal Processing, 2002
Multiuser detection for space-time coded synchronous multiple-access systems in the presence of independent Rayleigh fading is considered. Under the assumption of quasi-static fading, it is shown that optimal (full diversity achieving) space-time codes ...

Burst-by-Burst Adaptive Multiuser Detection CDMA: A Framework for Existing and Future Wireless Standards

, 2003
This paper provides a broad overview of the multiuser detection literature of the past few years in a nonmathematical, easily accessible approach. The treatment is then extended to the comparative study of channel-quality controlled burst-by-burst (BbB ...
