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…
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…
Joint Transmit Beamforming and Receive Power Splitting for MISO SWIPT Systems
Qingjiang Shi, Liang Liu, Weiqiang Xu +1
This paper studies a multi-user multiple-input single-output (MISO) downlink system for simultaneous wireless information and power transfer (SWIPT), in which a set of single-anten…
Probability-constrained Power Optimization for Multiuser MISO Systems with Imperfect CSI: A Bernstein Approximation Approach
Weiqiang Xu, Xiaodong Wang, Saleh Alshomrani
We consider power allocations in downlink cellular wireless systems where the basestations are equipped with multiple transmit antennas and the mobile users are equipped with singl…
Pricing-based Distributed Downlink Beamforming in Multi-Cell OFDMA Networks
Weiqiang Xu, Xiaodong Wang
We address the problem of downlink beamforming for mitigating the co-channel interference in multi-cell OFDMA networks. Based on the network utility maximization framework, we form…
