Scalable Power Control/Beamforming in Heterogeneous Wireless Networks with Graph Neural Networks
Xiaochen Zhang, Haitao Zhao, Jun Xiong +2
Machine learning (ML) has been widely used for efficient resource allocation (RA) in wireless networks. Although superb performance is achieved on small and simple networks, most e…
Fine Timing and Frequency Synchronization for MIMO-OFDM: An Extreme Learning Approach
Jun Liu, Kai Mei, Xiaochen Zhang +4
Multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) is a key technology component in the evolution towards cognitive radio (CR) in next-generation…
Performance Analysis on Machine Learning-Based Channel Estimation
Kai Mei, Jun Liu, Xiaochen Zhang +2
Recently, machine learning-based channel estimation has attracted much attention. The performance of machine learning-based estimation has been validated by simulation experiments.…
High-precision timing and frequency synchronization method for MIMO-OFDM systems in double-selective channels
Jun Liu, Kai Mei, Xiaochen Zhang +3
In this letter, a novel synchronization method for MIMO-OFDM systems is proposed. The new approach has an accurate estimate of both symbol timing and large frequency offest. Simula…
