Discrete Aware Tensor Completion via Convexized -Norm Approximation
Niclas Führling, Getuar Rexhepi, Giuseppe Abreu
We consider a novel algorithm, for the completion of partially observed low-rank tensors, where each entry of the tensor can be chosen from a discrete finite alphabet set, such as…
Quantization-Aided Secrecy: FD C-RAN Communications with Untrusted Radios
Omid Taghizadeh, Tianyu Yang, Hiroki Iimori +3
In this work, we study a full-duplex (FD) cloud radio access network (C-RAN) from the aspects of infrastructure sharing and information secrecy, where the central unit utilizes FD…
Full-Duplex Amplify-and-Forward MIMO Relaying: Impairments Aware Design and Performance Analysis
Omid Taghizadeh, Slawomir Stanczak, Hiroki Iimori +1
Full-Duplex (FD) Amplify-and-Forward (AF) Multiple-Input Multiple-Output (MIMO) relaying has been the focus of several recent studies, due to the potential for achieving a higher s…
Discrete-Aware Matrix Completion via Proximal Gradient
Hiroki Iimori, Giuseppe Thadeu Freitas de Abreu, Omid Taghizadeh +1
We present a novel algorithm for the completion of low-rank matrices whose entries are limited to a finite discrete alphabet. The proposed method is based on the recently-emerged p…
6G White paper: Research challenges for Trust, Security and Privacy
Mika Ylianttila, Raimo Kantola, Andrei Gurtov +24
The roles of trust, security and privacy are somewhat interconnected, but different facets of next generation networks. The challenges in creating a trustworthy 6G are multidiscipl…
Fractional Programming for Robust TX BF Design in Multi-User/Single-Carrier PD-NOMA
Hiroki Iimori, Giuseppe Abreu, Koji Ishibashi
We present a new Beamforming-based (BB) Multiple-Input Single-Output (MISO)-Non-orthogonal Multiple Access (NOMA) scheme for Power Domain NOMA (PD-NOMA), in which the total transmi…
