Ultra-High Resolution Method for Multipath Within a Co-Delay-Doppler Bin in DFT-P-OCDM
Mingxuan Han, Weile Zhang, Feifei Gao
Communication systems can reuse their transmitted signals for sensing without dedicated radar transmissions. For an established DFT-preprocessed orthogonal chirp division multiplex…
Multi-Antenna Covert Communications with Random Access Protocol
Weile Zhang, Nan Zhao, Shun Zhang +1
In this paper, we consider the issue of covert communications with random access protocol. We consider that the legitimate user Bob has no priori knowledge about packet arrival tim…
Time-Varying Massive MIMO Channel Estimation: Capturing, Reconstruction and Restoration
Muye Li, Shun Zhang, Nan Zhao +2
On the time-varying channel estimation, the traditional downlink (DL) channel restoration schemes usually require the reconstruction for the covariance of downlink process noise ve…
High-Mobility Wideband Massive MIMO Communications: Doppler Compensation, Analysis and Scaling Law
Wei Guo, Weile Zhang, Pengcheng Mu +2
In this paper, we apply angle-domain Doppler compensation for high-mobility wideband massive multi-input multi-output (MIMO) uplink transmission. The time-varying multipath channel…
Angle-Domain Doppler Pre-Compensation for High-Mobility OFDM Uplink with a Massive ULA
Wei Guo, Weile Zhang, Pengcheng Mu +2
In this paper, we propose a Doppler pre-compensation scheme for high-mobility orthogonal frequency division multiplexing (OFDM) uplink, where a high-speed terminal transmits signal…
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…
High-Mobility OFDM Downlink Transmission with Large-Scale Antenna Array
Wei Guo, Weile Zhang, Pengcheng Mu +1
In this correspondence, we propose a new receiver design for high-mobility orthogonal frequency division multiplexing (OFDM) downlink transmissions with a large-scale antenna array…
