Optimal Multi-Antenna Transmission for the Cooperative Non-Orthogonal Multiple-Access System
Applied Sciences, 2021 We investigate the beamforming for the multi antenna cooperative non-orthogonal multiple access (NOMA) system, where an access point (AP) delivers messages for multiple user terminals (UT) with successive interference cancellation (SIC) reception method.

Multiple-Symbol Differential Sphere Detection Aided Successive Relaying in the Cooperative DS-CDMA Uplink [PDF]
, 2011 The conventional amplify-and-forward cooperative system is capable of achieving a superior performance with the aid of Multiple-Symbol Differential Sphere Detection (MSDSD), when compared to conventional differential detection (CDD) for transmission over

On the achievable diversity-multiplexing tradeoff in half-duplex cooperative channels [PDF]
IEEE Transactions on Information Theory, 2005 We propose novel cooperative transmission protocols for delay-limited coherent fading channels consisting of N (half-duplex and single-antenna) partners and one cell site. In our work, we differentiate between the relay, cooperative broadcast (down-link),

DMT Optimal On-Demand Relaying for Mesh Networks [PDF]
, 2009 This paper presents a new cooperative MAC (Medium Access Control) protocol called BRIAF (Best Relay based Incremental Amplify-and-Forward). The proposed protocol presents two features: on-demand relaying and selection of the best relay terminal.

Delay- and Diversity-Aware Buffer-Aided Relay Selection Policies in Cooperative Networks
IEEE Access, 2018 Buffer-Aided (BA) relaying has shown tremendous performance improvements in terms of throughput and outage probability, although it has been criticized of suffering from long delays that are restrictive for applications, such as video streaming, Web ...

Cooperative diversity with opportunistic relaying [PDF]
IEEE Wireless Communications and Networking Conference, 2006. WCNC 2006., 2006 In this paper, we present single-selection-opportunistic-relaying with decode-and-forward (DaF) and amplify-and-forward (AaF) protocols under an aggregate power constraint. We show that opportunistic DaF relaying is equivalent to the outage bound of the optimal DaF strategy using all potential relays.
