Energy-Efficient Beamforming and Resource Optimization for AmBSC-Assisted Cooperative NOMA IoT Networks
Muhammad Asif, Asim Ihsan, Wali Ullah Khan +3
In this manuscript, we present an energy-efficient alternating optimization framework based on the multi-antenna ambient backscatter communication (AmBSC) assisted cooperative non-…
Energy-Efficient Backscatter-Assisted Coded Cooperative-NOMA for B5G Wireless Communications
Muhammad Asif, Asim Ihsan, Wali Ullah Khan +3
In this manuscript, we propose an alternating optimization framework to maximize the energy efficiency of a backscatter-enabled cooperative Non-orthogonal multiple access (NOMA) sy…
A Parallel Distributed Algorithm for the Power SVD Method
Jiaying Li, Sissi Xiaoxiao Wu, Qiang Li +1
In this work, we study how to implement a distributed algorithm for the power method in a parallel manner. As the existing distributed power method is usually sequentially updating…
Quartic Perturbation-based Outage-constrained Robust Design in Two-hop One-way Relay Networks
Sissi Xiaoxiao Wu, Sherry Xue-Ying Ni, Jiaying Li +1
In this work, we study a classic robust design problem in two-hop one-way relay system. We are particularly interested in the scenario where channel uncertainty exists in both the…
Full-Duplex Bidirectional Secure Communications under Perfect and Distributionally Ambiguous Eavesdropper's CSI
Qiang Li, Ying Zhang, Jingran Lin +1
Consider a full-duplex (FD) bidirectional secure communication system, where two communication nodes, named Alice and Bob, simultaneously transmit and receive confidential informat…
Semidefinite Relaxation and Approximation Analysis of a Beamformed Alamouti Scheme for Relay Beamforming Networks
Sissi Xiaoxiao Wu, Anthony Man-Cho So, Jiaxian Pan +1
In this paper, we study the amplify-and-forward (AF) schemes in two-hop one-way relay networks. In particular, we consider the multigroup multicast transmission between long-distan…
