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…
Asymptotic Rate Analysis for Impairments-Aware Multi-Carrier FD Massive MIMO Relay Networks utilizing MRT/MRC Strategy
Vimal Radhakrishnan, Omid Taghizadeh, Rudolf Mathar
In this paper, we analyze the asymptotic rate for a multi-carrier (MC) full-duplex (FD) massive multiple input multiple output (mMIMO) decode and forward (DF) relay system which se…
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…
Rate Splitting for Massive MIMO Multi-carrier system using Full Duplex Decode and Forward Relay with Hardware Impairments
Vimal Radhakrishnan, Omid Taghizadeh, Rudolf Mathar
In this paper, we address the power allocation problem for a decode and forward (DF) relay system, where a massive multiple-input-multiple-output (mMIMO) multi-carrier (MC) base st…
Coexistence of MIMO Radar and FD MIMO Cellular Systems with QoS Considerations
Sudip Biswas, Keshav Singh, Omid Taghizadeh +1
In this work, the feasibility of spectrum sharing between a multiple-input multiple-output (MIMO) radar system (RS) and a MIMO cellular system (CS), comprising of a full duplex (FD…
