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…
Distributed Optimal Rate-Reliability-Lifetime Tradeoff in Wireless Sensor Networks
Weiqiang Xu, Qingjiang Shi, Xiaoyun Wei +1
The transmission rate, delivery reliability and network lifetime are three fundamental but conflicting design objectives in energy-constrained wireless sensor networks. In this pap…
