Max-Min Fairness for IRS-Assisted Secure Two-Way Communications
Harindu Jayarathne, Tharindu Wickremasinghe, Kasun T. Hemachandra +2
This paper investigates an intelligent reflective surface (IRS) assisted secure multi-user two-way communication system. The aim of this paper is to enhance the physical layer secu…
Cluster-based Wireless Energy Transfer for Low Complex Energy Receivers
Samith Abeywickrama, Tharaka Samarasinghe, Chau Yuen +1
This paper proposes a novel channel estimation method and a cluster-based opportunistic scheduling policy, for a wireless energy transfer (WET) system consisting of multiple low-co…
Wireless Energy Transfer to a Pair of Energy Receivers using Signal Strength Feedback
Chanaka Singhabahu, Tharaka Samarasinghe, Samith Abeywickrama +1
This paper focuses on wireless energy transfer (WET) to a pair of low complex energy receivers (ER), by only utilizing received signal strength indicator (RSSI) values that are fed…
Wireless Energy Beamforming using Received Signal Strength Indicator Feedback
Samith Abeywickrama, Tharaka Samarasinghe, Chin Keong Ho +1
Multiple antenna techniques that allow energy beamforming have been looked upon as a possible candidate for increasing the transfer efficiency between the energy transmitter (ET) a…
Optimizing user selection schemes in vector broadcast channels
Meng Wang, Tharaka Samarasinghe, Jamie S. Evans
In this paper, we focus on the ergodic downlink sum-rate performance of a system consisting of a set of heterogeneous users. We study three user selection schemes to group near-ort…
Transmission Rank Selection for Opportunistic Beamforming with Quality of Service Constraints
Meng Wang, Tharaka Samarasinghe, Jamie Evans
In this paper, we consider a multi-cell multi-user MISO broadcast channel. The system operates according to the opportunistic beamforming framework in a multi-cell environment with…
