Journal ArticleDOI
On the Efficiency of Far-Field Wireless Power Transfer
Minghua Xia,Sonia Aissa +1 more
TL;DR: The channel variety among UEs inherent to the wireless environment can be exploited by opportunistic scheduling to significantly improve the power transfer efficiency when designing future wireless communication systems in support of simultaneous power and data transfer.
Journal ArticleDOI
Wirelessly Powered Two-Way Communication With Nonlinear Energy Harvesting Model: Rate Regions Under Fixed and Mobile Relay
TL;DR: The achievable rate region of wirelessly powered two-way communication with a fixed relay is derived and the gain is precisely quantified, and it is possible to quantify the relative advantage of spending energy on moving versus on transmission in wirelesslypowered two- way communication.
Journal ArticleDOI
Learning-Based Privacy-Aware Offloading for Healthcare IoT With Energy Harvesting
TL;DR: This scheme enables a healthcare IoT device to choose the offloading rate that improves the computation performance, protects user privacy, and saves the energy of the IoT device without being aware of the privacy leakage, IoT energy consumption, and edge computation model.
Journal ArticleDOI
Cooperative AF Relaying in Spectrum-Sharing Systems: Performance Analysis under Average Interference Power Constraints and Nakagami-m Fading
Minghua Xia,Sonia Aissa +1 more
TL;DR: The results show that system performance is dominated by the resource constraints and it improves slowly with increasing average SNR and larger Nakagami-m fading parameter on interference channels deteriorates system performance slightly, while opportunistic relay selection can be exploited to improve system performance significantly.
Journal ArticleDOI
Cooperative AF Relaying in Spectrum-Sharing Systems: Outage Probability Analysis under Co-Channel Interferences and Relay Selection
Minghua Xia,Sonia Aissa +1 more
TL;DR: It is revealed that it is the tolerable interference powers at primary receivers that dominate the system performance, rather than the CCIs from primary transmitters, which will benefit system designers in planning and designing next-generation broadband spectrum-sharing systems.
