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…
High-Mobility Massive MIMO Communications:Doppler Compensation and Transmit Diversity
Weile Zhang, Zhinan Hu, Shun Zhang +1
High-mobility wireless communications have been receiving a lot attentions. In this paper, we consider the highmobility uplink transmission from a high-speed terminal (HST) to a ba…
Time-Varying Downlink Channel Tracking for Quantized Massive MIMO Networks
Jianpeng Ma, Shun Zhang, Hongyan Li +2
This paper proposes a Bayesian downlink channel estimation algorithm for time-varying massive MIMO networks. In particular, the quantization effects at the receiver are considered.…
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…
