Joint Resource Allocation for Multiuser Opportunistic Beamforming Systems with OFDM-NOMA
Entropy, 2021 Opportunistic beamforming (OBF) is an effective technique to improve the spectrum efficiencies (SEs) of multiple-input-multiple-output (MIMO) systems, which can obtain multiuser diversity gains with both low computation complexity and feedback ...

A low complexity approach of combining cooperative diversity and multiuser diversity in multiuser cooperative networks [PDF]
, 2013 In this paper, we investigate the scheduling scheme to combine cooperative diversity (CD) and multiuser diversity (MUD) in multiuser cooperative networks under the time resource allocation (TRA) framework in which the whole transmission is divided into ...

Journal of Communications and Networks, 2001 In this paper, we propose a novel scheme for iterative multiuser detection and turbo decoding. Multiuser detection is based on the soft output maximum a posteriori (MAP) detector, which passes soft metrics to the single-user turbo decoders. Parallel concatenated convolutional codes (PCCC) are employed as single user turbo-codes, where each user is ...
