Beyond MMSE: Rank-1 Subspace Channel Estimator for Massive MIMO Systems
Bin Li, Ziping Wei, Shaoshi Yang +4
To glean the benefits offered by massive multi-input multi-output (MIMO) systems, channel state information must be accurately acquired. Despite the high accuracy, the computationa…
High-Performance Low-Complexity Hierarchical Frequency Synchronization for Distributed Massive MIMO-OFDMA Systems
Xiao-Yang Wang, Shaoshi Yang, Tian-Hao Yuan +3
We propose a high-performance yet low-complexity hierarchical frequency synchronization scheme for orthogonal frequency-division multiple-access (OFDMA) aided distributed massive m…
A Belief Propagation Based Framework for Soft Multiple-Symbol Differential Detection
Chanfei Wang, Tiejun Lv, Hui Gao +1
Soft noncoherent detection, which relies on calculating the \textit{a posteriori} probabilities (APPs) of the bits transmitted with no channel estimation, is imperative for achievi…
Detecting Byzantine Attacks Without Clean Reference
Ruohan Cao, Tan F. Wong, Tiejun Lv +2
We consider an amplify-and-forward relay network composed of a source, two relays, and a destination. In this network, the two relays are untrusted in the sense that they may perfo…
An ESPRIT-Based Approach for 2-D Localization of Incoherently Distributed Sources in Massive MIMO Systems
Anzhong Hu, Tiejun Lv, Hui Gao +2
In this paper, an approach of estimating signal parameters via rotational invariance technique (ESPRIT) is proposed for two-dimensional (2-D) localization of incoherently distribut…
