DOA and Polarization Estimation for Non-Circular Signals in 3-D Millimeter Wave Polarized Massive MIMO Systems
Liangtian Wan, Kaihui Liu, Ying-Chang Liang +1
In this paper, an algorithm of multiple signal classification (MUSIC) is proposed for two-dimensional (2-D) direction of- arrival (DOA) and polarization estimation of non-circular…
Backscatter Multiplicative Multiple-Access Systems: Fundamental Limits and Practical Design
Wanchun Liu, Ying-Chang Liang, Yonghui Li +1
In this paper, we consider a novel ambient backscatter multiple-access system, where a receiver (Rx) simultaneously detects the signals transmitted from an active transmitter (Tx)…
Applications of Economic and Pricing Models for Resource Management in 5G Wireless Networks: A Survey
Nguyen Cong Luong, Ping Wang, Dusit Niyato +3
This paper presents a comprehensive literature review on applications of economic and pricing theory for resource management in the evolving fifth generation (5G) wireless networks…
Channel Estimation for TDD/FDD Massive MIMO Systems with Channel Covariance Computing
Hongxiang Xie, Feifei Gao, Shi Jin +2
In this paper, we propose a new channel estimation scheme for TDD/FDD massive MIMO systems by reconstructing uplink/downlink channel covariance matrices (CCMs) with the aid of arra…
Modulation in the Air: Backscatter Communication over Ambient OFDM Carrier
Gang Yang, Ying-Chang Liang, Rui Zhang +1
Ambient backscatter communication (AmBC) enables radio-frequency (RF) powered backscatter devices (BDs) (e.g., sensors, tags) to modulate their information bits over ambient RF car…
End-to-end Throughput Maximization for Underlay Multi-hop Cognitive Radio Networks with RF Energy Harvesting
Chi Xu, Meng Zheng, Wei Liang +2
This paper studies a green paradigm for the underlay coexistence of primary users (PUs) and secondary users (SUs) in energy harvesting cognitive radio networks (EH-CRNs), wherein b…
