Joint Source-Relay Design for Full--Duplex MIMO AF Relay Systems
Qingjiang Shi, Mingyi Hong, Xiqi Gao +3
The performance of full-duplex (FD) relay systems can be greatly impacted by the self-interference (SI) at relays. By exploiting multi-antenna in FD relay systems, the spectral eff…
Dynamic Optimization For Heterogeneous Powered Wireless Multimedia Sensor Networks With Correlated Sources and Network Coding
Weiqiang Xu, Yushu Zhang, Qingjiang Shi +1
The energy consumption in wireless multimedia sensor networks (WMSN) is much greater than that in traditional wireless sensor networks. Thus, it is a huge challenge to remain the p…
Cross-Layer Control for Worse Case Delay Guarantees in Heterogeneous Powered Wireless Sensor Network via Lyapunov Optimization
Weiqiang Xu, Jianchen Tu, Qingjiang Shi
The delay guarantee is a challenge in wireless sensor networks (WSNs), where energy constraints must be considered. The coexistence of renewable energy and electricity grid is expe…
Secure Beamforming For MIMO Broadcasting With Wireless Information And Power Transfer
Qingjiang Shi, Weiqiang Xu, Jinsong Wu +2
This paper considers a basic MIMO information-energy (I-E) broadcast system, where a multi-antenna transmitter transmits information and energy simultaneously to a multi-antenna in…
