On June 2024, I received the Ph.D. degree in the College of Information Science & Electronic Engineering (ISEE) at Zhejiang University, Hangzhou, China, where I am jointly advised by Prof. Zhiguo Shi (Vice dean of the College of ISEE), Prof. Quan Yu (Academician of the Chinese Academy of Engineering), and Prof. Chengwei Zhou. From Oct. 2022 to Oct. 2023, I was a joint training Ph.D. student in the Department of Acoustics & Signal Processing at Aalto University, Espoo, Finland, where I am supervised by Prof. Sergiy Vorobyov (IEEE Fellow).

My research interests include array signal processing, tensor signal processing, and AI for signal processing. To effectively process large-scale high-dimensional array signals in future communication and sensing systems, I developed the theories of sub-Nyquist tensor processing, efficient tensor optimization, and resource-efficient tensorized neural networks. The proposed methods facilitate direction-of-arrival (DOA) estimation, adaptive beamforming, and channel estimation with low system costs and competitive performance, laying the foundations for wireless communication, target localization, and anti-interference.

I have published 20+ papers at top journals and international conferences with google citations .

I am an active reviewer for IEEE TSP, IEEE TAES, IEEE TVT, IEEE SPL, Signal Processing, and IET Signal processing.

💬 Research Highlights

Sub-Nyquist tensor DOA estimation

• Derive the high-order co-array tensor from sub-Nyquist tensor signals, and achieve co-array tensor-based direction-of-arrival estimation with high accuracy, super resolution and increased degrees-of-freedom
• Optimize the uniqueness condition of co-array tensor decomposition, and identify multiple sources that exceed the number of physical array sensors
• Complete the coarray tensor with missing slices to exploit the full co-array information

Analytical and numerical results are presented in our papers published in IEEE TSP, IEEE TAES, and IEEE ICASSP.

Sub-Nyquist tensor beamforming

• Develop the principle of tensor signal filtering with sparse array, thereby enhancing the signal-of-interest with reduced system burden
• Enhance mainlobe while suppressing sidelobes in the beampattern by solving tensor beamformer weight optimization problems
• Improve output signal-to-interference-plus-noise ratio (SINR) for strong anti-interference

The algorithm for beamforming design and results are presented in our papers published on IEEE TSP and Radarconf.

Tensorized neural networks for signal processing

• Design tensorized neural networks to efficiently learn inherent features from multi-dimensional array signals, leading to robust performance in non-ideal situations such as low signal-to-noise (SNR) ratio and limited snapshots
• Highly compress the parameters in tensorized neural layers, and accelerate the training speed of the tensorized neural network
