Two approaches to multiuser detection over fading channels
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2021 In this paper, two different receiver structures to multiuser detection that are appropriate for the code-division multiple-access systems with antenna arrays in fading channels are investigated and compared. We analyze and compare the performance of the

DSP-based ionospheric radiolink using DS-CDMA and on-line channel estimation [PDF]
, 2000 In this paper, a new blind multiuser detection algorithm is presented. It can both cancel multiuser interference and estimate the multipath channel response in a blind way. The method has been specially conceived for low coherence bandwidth channels such

Generating functional analysis of CDMA detection dynamics [PDF]
, 2005 We investigate the detection dynamics of the parallel interference canceller (PIC) for code-division multiple-access (CDMA) multiuser detection, applied to a randomly spread, fully syncronous base-band uncoded CDMA channel model with additive white ...

On robust multiuser detection [PDF]
Conference Record of the Thirty-Fourth Asilomar Conference on Signals, Systems and Computers (Cat. No.00CH37154), 2002 We study the design of multiuser detectors from an H/sup /spl infin// point of view. The H/sup /spl infin// approach is most appropriate in the situations where the statistical properties of the disturbances are not known or are too hard to model and analyze.

Non-Orthogonal Multiple Access With Sequence Block Compressed Sensing Multiuser Detection for 5G
IEEE Access, 2018 Compressed sensing-based multiuser detection (CSMUD) is a promising candidate to enable grant-free non-orthogonal multiple access for massive machine-type communication in the fifth-generation (5G) wireless communication system.

Exploiting Opportunistic Multiuser Detection in Decentralized Multiuser MIMO Systems [PDF]
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009 This paper studies the design of a decentralized multiuser multi-antenna (MIMO) system for spectrum sharing over a fixed narrow band, where the coexisting users independently update their transmit covariance matrices for individual transmit-rate maximization via an iterative manner.
