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.

A Hybrid Approach to Spatial Multiplexing in Multiuser MIMO Downlinks
EURASIP Journal on Wireless Communications and Networking, 2004 In the downlink of a multiuser multiple-input multiple-output (MIMO) communication system, simultaneous transmission to several users requires joint optimization of the transmitted signals. Allowing all users to have multiple antennas adds an additional
