Interference Channels With Full-Duplex Amplify-and-Forward Receiver Cooperations
IEEE Access, 2020 This paper considers a two-transmitter and two-receiver interference channel (IC), where each transmitter sends a message to its desired receiver. In particular, the full-duplex (FD) amplify-and-forward (AF) protocol is adopted to build up the receiver ...

IEICE Transactions on Communications, 2010 In this letter, we analyze the error performance of a code combining based cooperative diversity protocol. For coded transmission schemes, code-combining can obtain a near optimal low rate code by combining repeated codewords. An analytical method for evaluating the performances of such scheme is presented.

Cooperative Detection for Primary User in Cognitive Radio Networks
EURASIP Journal on Wireless Communications and Networking, 2009 We propose two novel cooperative detection schemes based on the AF (Amplify and Forward) and DF (Decode and Forward) protocols to achieve spatial diversity gains for cognitive radio networks, which are referred to as the AF-CDS, (AF-based Cooperative ...

Destination Assisted Jamming and Beamforming for Improving the Security of AF Relay Systems
IEEE Access, 2017 In this paper, we propose a destination-assisted jamming and beamforming (DAJB) scheme for physical layer security in a one-way cooperative amplify-and-forward (AF) relay communication system. The system model consists of one source, one destination, one

Multicast Transmissions With Full-Duplex Amplify-and-Forward User Cooperation
IEEE Access, 2020 In order to improve the multicast transmissions, a full-duplex (FD) user cooperation scheme is proposed. In this paper, the transmitter sends the common messages to two FD users, and each user forwards its received signals to its counterpart by amplify ...

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.

Journal of information and communication convergence engineering, 2013 Cognitive radio has been recently considered a promising technology to improve spectrum utilization by enabling secondary access to licensed bands that are not used by primary users temporarily or spatially. A prerequisite to this secondary access is the lack of interference to the primary system.

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 ...
