NOMA-Based User Cooperation With Incremental Hybrid Forwarding Protocols
IEEE Open Journal of the Communications Society, 2021 In this paper, we investigate the performance of a non-orthogonal multiple access (NOMA) wireless system, in which signal transmission of a far user is assisted by a near user.

Relay Cooperative Beamforming Algorithm Based on Probabilistic Constraint in SWIPT Secrecy Networks
IEEE Access, 2020 We explore physical layer security of simultaneous wireless information and power transfer (SWIPT) relay network in this paper. Modeling channel error between relay and eavesdroppers (Eves) as random channel state information (CSI) error, we present an ...

Power Allocation for Cognitive Collaborative Network Based on Adaptive Relay [PDF]
Jisuanji gongcheng, 2017 In relayed transmission systems,power allocation algorithm based on Decode and Forward(DF) increases error in case of incorrect decoding of the information symbols,and the one based on Amplify Forward(AF) amplifies the noise.In order to solve the problem,

Pattern Division Multiple Access Featuring Amplify-and-Forward Relaying in an Uplink Network
IEEE Access, 2020 NOMA is one of key enabling technologies for prosumer energy management. We studied co-operative techniques useful for establishing pattern division multiple access (PDMA) in an uplink network. In particular, we examined amplify-and-forward (AF) relaying
