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 ...

Large-System Analysis of Multiuser Detection with an Unknown Number of Users: A High-SNR Approach [PDF]
, 2010 We analyze multiuser detection under the assumption that the number of users accessing the channel is unknown by the receiver. In this environment, users' activity must be estimated along with any other parameters such as data, power, and location.
