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…
Opportunistic AP Selection in Cell-Free Massive MIMO-OFDM Systems
Wei Jiang, Hans D. Schotten
Exploiting the degree of freedom in the frequency domain and the near-far effect among different access points (APs), this paper proposes an opportunistic transmission scheme in ce…
Impact of Channel Aging on Zero-Forcing Precoding in Cell-Free Massive MIMO Systems
Wei Jiang, Hans Dieter Schotten
In the context of cell-free massive multi-input multi-output (mMIMO), zero-forcing precoding (ZFP) requires the exchange of instantaneous channel state information and precoded dat…
Cell-Free Massive MIMO-OFDM Transmission over Frequency-Selective Fading Channels
Wei Jiang, Hans Dieter Schotten
This letter presents and analyzes orthogonal frequency-division multiplexing (OFDM)-based multi-carrier transmission for cell-free massive multi-input multi-output (CFmMIMO) over f…
A Simple Cooperative Diversity Method Based on Deep-Learning-Aided Relay Selection
Wei Jiang, Hans Dieter Schotten
Opportunistic relay selection (ORS) has been recognized as a simple but efficient method for mobile nodes to achieve cooperative diversity in slow fading channels. However, the wro…
Predictive Relay Selection: A Cooperative Diversity Scheme Using Deep Learning
Wei Jiang, Hans Dieter Schotten
In this paper, we propose a novel cooperative multi-relay transmission scheme for mobile terminals to exploit spatial diversity. By improving the timeliness of measured channel sta…
