Enhanced Group Sparse Beamforming for Green Cloud-RAN: A Random Matrix Approach
Yuanming Shi, Jun Zhang, Wei Chen +1
Group sparse beamforming is a general framework to minimize the network power consumption for cloud radio access networks (Cloud-RANs), which, however, suffers high computational c…
Non-parametric Message Important Measure: Storage Code Design and Transmission Planning for Big Data
Shanyun Liu, Rui She, Pingyi Fan +1
Storage and transmission in big data are discussed in this paper, where message importance is taken into account. Similar to Shannon Entropy and Renyi Entropy, we define non-parame…
Generalized Sparse and Low-Rank Optimization for Ultra-Dense Networks
Yuanming Shi, Jun Zhang, Wei Chen +1
Ultra-dense network (UDN) is a promising technology to further evolve wireless networks and meet the diverse performance requirements of 5G networks. With abundant access points, e…
Beyond Empirical Models: Pattern Formation Driven Placement of UAV Base Stations
Jiaxun Lu, Shuo Wan, Xuhong Chen +3
This work considers the placement of unmanned aerial vehicle base stations (UAV-BSs) with criterion of minimum UAV-recall-frequency (UAV-RF), indicating the energy efficiency of mo…
Hybrid Precoding in Millimeter Wave Systems: How Many Phase Shifters Are Needed?
Xianghao Yu, Jun Zhang, Khaled B. Letaief
Hybrid precoding has been recently proposed as a cost-effective transceiver solution for millimeter wave (mm-wave) systems. The analog component in such precoders, which is compose…
Layered Group Sparse Beamforming for Cache-Enabled Green Wireless Networks
Xi Peng, Yuanming Shi, Jun Zhang +1
The exponential growth of mobile data traffic is driving the deployment of dense wireless networks, which will not only impose heavy backhaul burdens, but also generate considerabl…
