Distributed Multiuser Two-Way AF Relaying Systems under Jamming Environment
A distributed multiuser two-way amplify-and-forward (AF) wireless relay strategy consisting of 2M sources (or 2M destinations) and N relays all equipped with single antenna per communication node is studied in this paper. All sources act as both sources and destinations with a self-interference cancelation process at the 2M destinations. The main objective is to design the closed-form of minimu...
متن کاملSubcarrier Allocation for Multiuser in Two-Way OFDMA Relay Networks using Decode-and-Forward Relaying
A two-way relay network provide improved spectral efficiency compared with a conventional one-way relay network by using either superposition coding or network coding. OFDMA network provides imptoved performance by adaptive resource allocation. In this paper, we propose a adaptive subcarrier allocation for a multiuser two-way OFDMA relay network. In the proposed algorithm, subcarriers are alloc...
متن کاملDistance-Aware Beamforming for Multiuser Secure Communication Systems
Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems) are possible alternatives to provide security for such applications. In this paper, we consid...
متن کاملMultiuser Two-Way AF Relaying Network with Multi-antenna Relay under Power Constraint
The two-way amplify-and-forward (AF) relaying network consisting of 2M sources with only a single antenna per source and one relay with multiple N antennas at the 2M destinations is investigated in this paper. All sources act as both sources and destinations with a self-interference cancelation process at the 2M destinations. The closed form of the relay amplifying matrix is optimized under the...
متن کاملJoint Source and Relay Precoding Design for One-Way Full-Duplex MIMO Relaying Systems
In this paper we address the sum rate maximization problem for a one-way amplify-and-forward relaying system with a full-duplex relay. This optimization problem which requires the joint source and relay precoding design is in general nonconvex. We propose different convex optimization based suboptimal schemes for different system settings. Moreover, we derive a gradient projection based algorit...
