Robust Beamforming for Wireless Information and Power Transmission
Zhengzheng Xiang, Meixia Tao
In this letter, we study the robust beamforming problem for the multi-antenna wireless broadcasting system with simultaneous information and power transmission, under the assumptio…
Coordinated Multicast Beamforming in Multicell Networks
Zhengzheng Xiang, Meixia Tao, Xiaodong Wang
We study physical layer multicasting in multicell networks where each base station, equipped with multiple antennas, transmits a common message using a single beamformer to multipl…
Linear Precoding Designs for Amplify-and-Forward Multiuser Two-Way Relay Systems
Rui Wang, Meixia Tao, Yongwei Huang
Two-way relaying can improve spectral efficiency in two-user cooperative communications. It also has great potential in multiuser systems. A major problem of designing a multiuser…
Spectrum Leasing and Cooperative Resource Allocation in Cognitive OFDMA Networks
Meixia Tao, Yuan Liu
This paper considers a cooperative OFDMA-based cognitive radio network where the primary system leases some of its subchannels to the secondary system for a fraction of time in exc…
Degrees of Freedom for MIMO Two-Way X Relay Channel
Zhengzheng Xiang, Meixia Tao, Jianhua Mo +1
We study the degrees of freedom (DOF) of a multiple-input multiple-output (MIMO) two-way X relay channel, where there are two groups of source nodes and one relay node, each equipp…
Cross-Layer Optimization of Two-Way Relaying for Statistical QoS Guarantees
Cen lin, Yuan Liu, Meixia Tao
Two-way relaying promises considerable improvements on spectral efficiency in wireless relay networks. While most existing works focus on physical layer approaches to exploit its c…
