Robust Beamforming for Physical Layer Security in BDMA Massive MIMO
Fengchao Zhu, Feifei Gao, Hai Lin +2
In this paper, we design robust beamforming to guarantee the physical layer security for a multiuser beam division multiple access (BDMA) massive multiple-input multiple-output (MI…
Spatial- and Frequency-Wideband Effects in Millimeter-Wave Massive MIMO Systems
Bolei Wang, Feifei Gao, Shi Jin +2
When there are a large number of antennas in massive MIMO systems, the transmitted wideband signal will be sensitive to the physical propagation delay of electromagnetic waves acro…
Full-Duplex Massive MIMO Relaying Systems with Low-Resolution ADCs
Chuili Kong, Caijun Zhong, Shi Jin +3
This paper considers a multipair amplify-and-forward massive MIMO relaying system with low-resolution ADCs at both the relay and destinations. The channel state information (CSI) a…
Proactive Eavesdropping in Relaying Systems
Xin Jiang, Hai Lin, Caijun Zhong +2
This paper investigates the performance of a legitimate surveillance system, where a legitimate monitor aims to eavesdrop on a dubious decode-and-forward relaying communication lin…
Frequency Synchronization for Uplink Massive MIMO Systems
Weile Zhang, Feifei Gao, Shi Jin +1
In this paper, we propose a frequency synchronization scheme for multiuser orthogonal frequency division multiplexing (OFDM) uplink with a large-scale uniform linear array (ULA) at…
Uncoordinated Frequency Shifts based Pilot Contamination Attack Detection
Weile Zhang, Hai Lin
Pilot contamination attack is an important kind of active eavesdropping activity conducted by a malicious user during channel training phase. In this paper, motivated by the fact t…
A New View of Multi-User Hybrid Massive MIMO: Non-Orthogonal Angle Division Multiple Access
Hai Lin, Feifei Gao, Shi Jin +1
This paper presents a new view of multi-user (MU) hybrid massive multiple-input and multiple-output (MIMO) systems from array signal processing perspective. We first show that the…
