Blind adaptive receiver for uplink multiuser massive MIMO systems

open access: yesETRI Journal, 2019
Herein, we consider uplink multiuser massive multiple‐input multiple‐output systems when multiple users transmit information symbols to a base station (BS) by applying simple space‐time block coding (STBC).

Semi-Blind HEBB-PPIC Multiuser Detection Algorithm

open access: yesEnergy Procedia, 2012
AbstractInter-cell interference greatly impairs the capacity of CDMA system. 4G era is coming with much severer inter-cell inte-rference, and it's important to find a good solution to inter-cell Interference cancellation. In this paper, the semiblind Hebb-PPIC Multi-User Detection(MUD algorithm which applied in the CDMA uplink is proposed.

A Subspace Approach to Blind Multiuser Detection for Ultra-Wideband Communication Systems

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
Impulse radio-based ultra-wideband (UWB) communication systems allow multiple users to access channels simultaneously by assigning unique time-hopping codes to individual users, while each user's information stream is modulated by pulse-position ...

Stability Properties of Network Diversity Multiple Access with Multiple-Antenna Reception and Imperfect Collision Multiplicity Estimation

open access: yesJournal of Computer Networks and Communications, 2013
In NDMA (network diversity multiple access), protocol-controlled retransmissions are used to create a virtual MIMO (multiple-input multiple-output) system, where collisions can be resolved via source separation.

Turbo-coded blind per-survivor processing multiuser detection CDMA

open access: yes11th IEEE International Symposium on Personal Indoor and Mobile Radio Communications. PIMRC 2000. Proceedings (Cat. No.00TH8525), 2002
Joint data and blind channel estimation based on the principle of per-survivor processing (PSP) is invoked and characterised in the proposed turbo-coded multiuser detection assisted code division multiple access (CDMA) system. The turbo-coded blind PSP receiver invoked the likelihood function in its metric calculations over the typical urban (TU) time ...
