When Full Duplex Wireless Meets Non-Orthogonal Multiple Access: Opportunities and Challenges
Xianhao Chen, Gang Liu, Zheng Ma +4
Non-orthogonal multiple access (NOMA) is a promising radio access technology for the 5G wireless systems. The core of NOMA is to support multiple users in the same resource block v…
Filtered-OFDM - Enabler for Flexible Waveform in The 5th Generation Cellular Networks
Xi Zhang, Ming Jia, Lei Chen +2
The underlying waveform has always been a shaping factor for each generation of the cellular networks, such as orthogonal frequency division multiplexing (OFDM) for the 4th generat…
Artificial-Noise-Aided Secure Multi-Antenna Transmission with Limited Feedback
Xi Zhang, Matthew R. McKay, Xiangyun Zhou +1
We present an optimized secure multi-antenna transmission approach based on artificial-noise-aided beamforming, with limited feedback from a desired single-antenna receiver. To dea…
On-Demand Based Wireless Resources Trading for Green Communications
Wenchi Cheng, Xi Zhang, Hailin Zhang +1
The purpose of Green Communications is to reduce the energy consumption of the communication system as much as possible without compromising the quality of service (QoS) for users.…
Base-Station Selections for QoS Provisioning Over Distributed Multi-User MIMO Links in Wireless Networks
Qinghe Du, Xi Zhang
We propose the QoS-aware BS-selection and the corresponding resource-allocation schemes for downlink multi-user transmissions over the distributed multiple-input-multiple-output (M…
Full Duplex Wireless Communications for Cognitive Radio Networks
Wenchi Cheng, Xi Zhang, Hailin Zhang
As a key in cognitive radio networks (CRNs), dynamic spectrum access needs to be carefully designed to minimize the interference and delay to the \emph{primary} (licensed) users. O…
