Full-Duplex Cloud Radio Access Network: Stochastic Design and Analysis
Arman Shojaeifard, Kai-Kit Wong, Wei Yu +2
Full-duplex (FD) has emerged as a disruptive communications paradigm for enhancing the achievable spectral efficiency (SE), thanks to the recent major breakthroughs in self-interfe…
Secure Full-Duplex Two-Way Relaying for SWIPT
Alexander A. Okandeji, Muhammad R. A. Khandaker, Kai-Kit Wong +3
This letter studies bi-directional secure information exchange in a simultaneous wireless information and power transfer (SWIPT) system enabled by a full-duplex (FD) multiple-input…
Secure Full-Duplex Device-to-Device Communication
Muhammad R. A. Khandaker, Christos Masouros, Kai-Kit Wong
This paper considers full-duplex (FD) device-to-device (D2D) communications in a downlink MISO cellular system in the presence of multiple eavesdroppers. The D2D pair communicate s…
Optimal Power Allocation by Imperfect Hardware Analysis in Untrusted Relaying Networks
Ali Kuhestani, Abbas Mohammadi, Kai-Kit Wong +3
By taking a variety of realistic hardware imperfections into consideration, we propose an optimal power allocation (OPA) strategy to maximize the instantaneous secrecy rate of a co…
Edge Caching in Dense Heterogeneous Cellular Networks with Massive MIMO Aided Self-backhaul
Lifeng Wang, Kai-Kit Wong, Sangarapillai Lambotharan +2
This paper focuses on edge caching in dense heterogeneous cellular networks (HetNets), in which small base stations (SBSs) with limited cache size store the popular contents, and m…
Secure Two-Way Transmission via Wireless-Powered Untrusted Relay and External Jammer
Milad Tatar Mamaghani, Ali Kuhestani, Kai-Kit Wong
In this paper, we propose a two-way secure communication scheme where two transceivers exchange confidential messages via a wireless powered untrusted amplify-and-forward (AF) rela…
