Adaptive Blind Multiuser Detection over Flat Fast Fading Channels Using Particle Filtering
EURASIP Journal on Wireless Communications and Networking, 2005 We propose a method for blind multiuser detection (MUD) in synchronous systems over flat and fast Rayleigh fading channels. We adopt an autoregressive-moving-average (ARMA) process to model the temporal correlation of the channels.

Analysys of Blind adaptive multiuser detection receivers [PDF]
Transactions on Machine Learning and Artificial Intelligence, 2014 In this paper, blind adaptive multiuser detection with Mean Output Energy (MOE) are designed in receivers for synchronous MC-DS-CDMA systems in Rayleigh fading channels. Pre and post detection in multiuser detectors are implemented in the system to detect their effects in the outputs.
