Semi-coherent Detection and Performance Analysis for Ambient Backscatter System
Jing Qian, Feifei Gao, Gongpu Wang +2
We study a novel communication mechanism, ambient backscatter, that utilizes radio frequency (RF) signals transmitted from an ambient source as both energy supply and information c…
Spatial-Temporal BEM and Channel Estimation Strategy for Massive MIMO Time-Varying Systems
Hongxiang Xie, Feifei Gao, Shun Zhang +1
This paper proposes a new channel estimation scheme for the multiuser massive multiple-input multiple-output (MIMO) systems in time-varying environment. We introduce a discrete Fou…
Design and Implementation of a TDD-Based 128-Antenna Massive MIMO Prototyping System
Xi Yang, Wen-Jun Lu, Ning Wang +7
Spurred by the dramatic mobile IP growth and the emerging Internet of Things (IoT) and cloud-based applications, wireless networking is witnessing a paradigm shift. By fully exploi…
Spectral Efficiency of Mixed-ADC Receivers for Massive MIMO Systems
Weiqiang Tan, Shi Jin, Chaokai Wen +1
This paper investigated the uplink of multi-user massive multi-input multi-output (MIMO) systems with a mixed analog-to-digital converter (ADC) receiver architecture, in which some…
Wireless Power Transfer in Massive MIMO Aided HetNets with User Association
Yongxu Zhu, Lifeng Wang, Kai-Kit Wong +2
This paper explores the potential of wireless power transfer (WPT) in massive multiple input multiple output (MIMO) aided heterogeneous networks (HetNets), where massive MIMO is ap…
Wireless Information and Power Transfer Design for Energy Cooperation Distributed Antenna Systems
Fangchao Yuan, Shi Jin, Kai-Kit Wong +1
Distributed antenna systems (DAS) have been widely implemented in state-of-the-art cellular communication systems to cover dead spots. Recent studies have also indicated that DAS h…
