Millimeter Wave Power Transfer and Information Transmission
Lifeng Wang, Maged Elkashlan, Robert W. Heath +2
Compared to the existing lower frequency wireless power transfer, millimeter wave (mmWave) power transfer takes advantage of the high-dimensional multi-antenna and narrow beam tran…
Wireless Powered Cooperative Jamming for Secrecy Multi-AF Relaying Networks
Hong Xing, Kai-Kit Wong, Arumugam Nallanathan +1
This paper studies secrecy transmission with the aid of a group of wireless energy harvesting (WEH)-enabled amplify-and-forward (AF) relays performing cooperative jamming (CJ) and…
Safeguarding Massive MIMO Aided HetNets Using Physical Layer Security
Yansha Deng, Lifeng Wang, Kai-Kit Wong +2
This paper exploits the potential of physical layer security in massive multiple-input multiple-output (MIMO) aided two-tier heterogeneous networks (HetNets). We focus on the downl…
Bayes-Optimal Joint Channel-and-Data Estimation for Massive MIMO with Low-Precision ADCs
Chao-Kai Wen, Chang-Jen Wang, Shi Jin +2
This paper considers a multiple-input multiple-output (MIMO) receiver with very low-precision analog-to-digital convertors (ADCs) with the goal of developing massive MIMO antenna s…
To Harvest and Jam: A Paradigm of Self-Sustaining Friendly Jammers for Secure AF Relaying
Hong Xing, Kai-Kit Wong, Zheng Chu +1
This paper studies the use of multi-antenna harvest-and-jam (HJ) helpers in a multi-antenna amplify-and-forward (AF) relay wiretap channel assuming that the direct link between the…
Joint Channel-and-Data Estimation for Large-MIMO Systems with Low-Precision ADCs
Chao-Kai Wen, Shi Jin, Kai-Kit Wong +2
The use of low precision (e.g., 1-3 bits) analog-to-digital convenors (ADCs) in very large multiple-input multiple-output (MIMO) systems is a technique to reduce cost and power con…
