A Frequency-Domain Opportunistic Approach for Spectral-Efficient Cell-Free Massive MIMO
Wei Jiang, Hans Dieter Schotten
Constrained by weak signal strength and significant inter-cell interference, users located at the cell edge in a cellular network suffer from inferior service quality. Recently, ce…
A Semantic Model for Physical Layer Deception
Bin Han, Yao Zhu, Anke Schmeink +2
Physical layer deception (PLD) is a novel security mechanism that combines physical layer security (PLS) with deception technologies to actively defend against eavesdroppers. In th…
Deep Learning-Aided Delay-Tolerant Zero-Forcing Precoding in Cell-Free Massive MIMO
Wei Jiang, Hans D. Schotten
In the context of cell-free massive multi-input multi-output (CFmMIMO), zero-forcing precoding (ZFP) is superior in terms of spectral efficiency. However, it suffers from channel a…
Performance Impact of Channel Aging and Phase Noise on Intelligent Reflecting Surface
Wei Jiang, Hans Dieter Schotten
This letter aims to clarify the impact of channel aging and phase noise on the performance of intelligent reflecting surface-aided wireless systems. We first model mathematically t…
Initial Access for Millimeter-Wave and Terahertz Communications with Hybrid Beamforming
Wei Jiang, Hans D. Schotten
In order to achieve terabits-per-second (Tbps) data rates in the sixth-generation (6G) mobile system, wireless communications are required to exploit the abundant spectrum in the m…
Initial Beamforming for Millimeter-Wave and Terahertz Communications in 6G Mobile Systems
Wei Jiang, Hans D. Schotten
To meet the demand of supreme data rates in terabits-per-second, the next-generation mobile system needs to exploit the abundant spectrum in the millimeter-wave and terahertz bands…
