Intersymbol Decorrelating Detector for Asynchronous CDMA Networks with Multipath
EURASIP Journal on Wireless Communications and Networking, 2005 Most reported multiuser detection techniques for CDMA systems need the channel estimation including the delay spread and the parameters of the multipath channel of the desired user. This paper proposes an intersymbol decorrelating detector that makes use

Blind Chip-Rate Multiuser Equalisation
, 2003 This paper addresses blind multiuser detection in a DS-CDMA downlink channel. The synchronous users are separated by re-establishing orthogonality of their spreading sequences in a common chip-rate equaliser.

An Iterative Multiuser Detector for Turbo-Coded DS-CDMA Systems
EURASIP Journal on Advances in Signal Processing, 2005 We propose an iterative multiuser detector for turbo-coded synchronous and asynchronous direct-sequence CDMA (DS-CDMA) systems. The receiver is derived from the maximum a posteriori (MAP) estimation of the single user's transmitted data, conditioned on ...

Exact Outage Performance Analysis of Multiuser Multi-relay Spectrum Sharing Cognitive Networks [PDF]
Radioengineering, 2015 In this paper, we investigate the outage performance of dual-hop multiuser multi-relay cognitive radio networks under spectrum sharing constraints. Using an efficient relay-destination selection scheme, the exact and asymptotic closed-form expressions ...
