Fluid Antenna-Enabled Backscatter Communication under Imperfect Channel Observations
Masoud Kaveh, Farshad Rostami Ghadi, Riku Jantti +2
Ambient backscatter communication (AmBC) enables ultra-low-power connectivity by allowing passive backscatter devices (BDs) to convey information through reflection of ambient sign…
On Performance of FAS-aided Wireless Powered NOMA Communication Systems
Farshad Rostami Ghadi, Masoud Kaveh, Kai-Kit Wong +2
This paper studies the performance of a wireless powered communication network (WPCN) under the non-orthogonal multiple access (NOMA) scheme, where users take advantage of an emerg…
QoS Aware Transmit Beamforming for Secure Backscattering in Symbiotic Radio Systems
Mingcheng Nie, Deepak Mishra, Azzam Al-nahari +2
This paper focuses on secure backscatter transmission in the presence of a passive multi-antenna eavesdropper through a symbiotic radio (SR) network. Specifically, a single-antenna…
Covert backscatter communication with directional MIMO
Roberto Di Candia, Saneea Malik, Huseyin Yiğitler +1
We study a backscatter communication protocol over a AWGN channel, where a transmitter illuminates a tag with a directional multi-antenna. The tag performs load modulation on the s…
Energy Efficiency Maximization of Full-Duplex Two-Way Relay With Non-Ideal Power Amplifiers and Non-Negligible Circuit Power
Qimei Cui, Yuhao Zhang, Wei Ni +2
In this paper, we maximize the energy efficiency (EE) of full-duplex (FD) two-way relay (TWR) systems under non-ideal power amplifiers (PAs) and non-negligible transmission-depende…
Multiantenna Quantum Backscatter Communications
Riku Jäntti, Roberto Di Candia, Ruifeng Duan +1
Quantum illumination (QI) is a revolutionary photonic quantum sensing paradigm that enhances the sensitivity of photodetection in noisy and lossy environments. The QI concept has b…
Packet Error Rate Analysis of Uncoded Schemes in Block-Fading Channels using Extreme Value Theory
Aamir Mahmood, Riku Jäntti
We present a generic approximation of the packet error rate (PER) function of uncoded schemes in the AWGN channel using extreme value theory (EVT). The PER function can assume both…
Design and Analysis of Downlink Channel Estimation Based on Parametric Model for Massive MIMO in FDD Systems
Yinsheng Liu, Yinjun Liu, Qimei Cui +1
This paper investigates downlink channel estimation in frequency-division duplex (FDD)-based massive multiple-input multiple-output (MIMO) systems. To reduce the overhead of downli…
On the Achievable Rate of Bi-Static Modulated Re-Scatter Systems
Ruifeng Duan, Riku Jäntti, Hüseyin Yiğitler +1
In ambient re-scatter communications, devices convey information by modulating and re-scattering the radio frequency signals impinging on their antennas. In this correspondence, we…
Asymptotic Analysis of Multi-Antenna Cognitive Radio Systems Using Extreme Value Theory
Ruifeng Duan, Zhong Zheng, Riku Jäntti +1
We consider a spectrum-sharing cognitive radio system with antenna selection applied at the secondary transmitter (ST). Based on the extreme value theory, we deduce a simple and ac…
Performance Analysis of Mean Value-Based Power Allocation with Primary User Interference in Spectrum Sharing Systems
Ruifeng Duan, Riku Jäntti, Mohammed S. Elmusrati
In this paper, we provide an exact expression for the ergodic capacity of the secondary user, and a unified closed-form expression for its bounds with taking the consideration of t…
