Principal Component Analysis (PCA)-based Massive-MIMO Channel Feedback
Jingon Joung, Ernest Kurniawan, Sumei Sun
Channel-state-information (CSI) feedback methods are considered, especially for massive or very large-scale multiple-input multiple-output (MIMO) systems. To extract essential info…
Stochastic Geometry-Based Performance Bounds for Non-Fading and Rayleigh Fading Ad Hoc Networks
Hieu Duy Nguyen, Sumei Sun
In this paper, we study the performance of non-fading and Rayleigh fading ad hoc networks. We first characterize the distribution of the signal-to-interference-plus-noise ratio (SI…
Massive MIMO versus Small-Cell Systems: Spectral and Energy Efficiency Comparison
Hieu Duy Nguyen, Sumei Sun
In this paper, we study the downlink performance of two important 5G network architectures, i.e. massive multiple-input multiple-output (M-MIMO) and small-cell densification. We pr…
Adaptively Directional Wireless Power Transfer for Large-scale Sensor Networks
Zhe Wang, Lingjie Duan, Rui Zhang
Wireless power transfer (WPT) prolongs the lifetime of wireless sensor network by providing sustainable power supply to the distributed sensor nodes (SNs) via electromagnetic waves…
Energy Group-Buying with Loading Sharing for Green Cellular Networks
Jie Xu, Lingjie Duan, Rui Zhang
In the emerging hybrid electricity market, mobile network operators (MNOs) of cellular networks can make day-ahead energy purchase commitments at low prices and real-time flexible…
Optimal Cell Clustering and Activation for Energy Saving in Load-Coupled Wireless Networks
Lei Lei, Di Yuan, Chin Keong Ho +1
Optimizing activation and deactivation of base station transmissions provides an instrument for improving energy efficiency in cellular networks. In this paper, we study optimal ce…
Multi-Antenna Wireless Energy Transfer for Backscatter Communication Systems
Gang Yang, Chin Keong Ho, Yong Liang Guan
We study RF-enabled wireless energy transfer (WET) via energy beamforming, from a multi-antenna energy transmitter (ET) to multiple energy receivers (ERs) in a backscatter communic…
Constant Envelope Precoding with Adaptive Receiver Constellation in MISO Fading Channel
Shuowen Zhang, Rui Zhang, Teng Joon Lim
Constant envelope (CE) precoding is an appealing transmission technique which enables the realization of high power amplifier (PA) efficiency. For CE precoding in a single-user mul…
Optimized Uplink Transmission in Multi-Antenna C-RAN with Spatial Compression and Forward
Liang Liu, Rui Zhang
Massive MIMO and C-RAN are two promising techniques for implementing future wireless communication systems, where a large number of antennas are deployed either being co-located at…
Heterogeneous Cellular Networks Using Wireless Backhaul: Fast Admission Control and Large System Analysis
Jian Zhao, Tony Q. S. Quek, Zhongding Lei
We consider a heterogeneous cellular network with densely underlaid small cell access points (SAPs). Wireless backhaul provides the data connection from the core network to SAPs. T…
