Biography

I am currently a Ph.D. student at NYU WIRELESS, New York University, under the supervision of Prof. Theodore S. Rappaport. This academic journey began in Fall 2023. I hold a B.Eng. degree with Honors from Chongqing University of Posts and Telecommunications, where I was under the guidance of Prof. Yongjun Xu during my undergraduate studies.

Research

My current research interests lie in the fields of waste factor, channel modeling, reconfigurable intelligent surfaces, resource allocation and backscatter communication, etc.

Projects

Waste Factor: A New Metric for Evaluating Power Efficiency in any Cascade (Jan. 2023 - Now)

• Supervisor: Prof. Theodore S. Rappaport (Member of US National Academy of Engineering, Founding Director of NYU WIRELESS, IEEE Fellow)
• Waste factor (W) is a novel metric to evaluate the power efficiency of any device or cascade.
• Enhanced W for data centers using power usage effectiveness (PUE), which won best paper.
• Simulated how component efficiency in a cascaded communication system influences the W at 28 GHz and 142 GH in a 1 km2 cellular cell.
• Extending W to analyze parallel cascade systems, and radio access network (RAN).

FR3 Radio Propagation Measurement and Modeling in 6.75 GHz and 16.95 GHz (Nov. 2023 - Now)

• Supervisor: Prof. Theodore S. Rappaport (Member of US National Academy of Engineering, Founding Director of NYU WIRELESS, IEEE Fellow)
• Operating and conducting a comprehensive FR3 measurement campaign at NYU.
• Creating a detailed statistical spatial channel model based on radio propagation data from outdoor, indoor, and factory environments together with penetration loss and cross-polarization discrimination (XPD) measurement at 6.75 GHz and 16.95 GHz.

Using AI and NYURay for Integrated Sensing and Communication (Sept. 2023 - Now)

• Supervisor: Prof. Theodore S. Rappaport (Member of US National Academy of Engineering, Founding Director of NYU WIRELESS, IEEE Fellow)
• Calibrating 3D ray-tracing tool NYURay to NYU campus for precise mapping and sensing.
• Developing a multi-task prediction model using AI for object positioning and classification.

Power Allocation and Frequency Reuse Scheme for 5G Networks (Jul. 2021 - Aug. 2021)

• Supervisor: Prof. Kai-Kit Wong (IEEE Fellow), UCL
• Deployed strict frequency reuse and soft frequency reuse with various novel power allocation algorithms in a multi-cell cellular network capacity simulation.
• Proposed a game theory-based forward-looking water-filling (WF) algorithm to largely decrease the computing complexity and self-optimize the WF algorithm to obtain higher capacity.

Undergraduate Thesis (Sept. 2022 -Jun. 2023)

• Supervisor: Prof. Yongjun Xu (IEEE Senior Member), CQUPT
• Developed and optimized an energy-efficient, wireless-powered backscatter communication network using OFDMA and robust optimization techniques, significantly improving network throughput and reducing outage probability under imperfect CSI.
• Utilized the Dinkelbach method and variable substitution to transform the resource allocation problem into a convex optimization problem, solved using the Lagrange dual method.
• Demonstrated superior performance and robustness through MATLAB simulations, outperforming traditional backscatter and harvest-then-transmit algorithms.

Research Training Program of CQUPT (Apr. 2021 - Apr. 2022)

• Supervisor: Prof. Yongjun Xu (IEEE Senior Member), CQUPT
• Proposed a joint radio resource and passive beamforming optimization scheme for a downlink RIS-assisted wireless powered communication network with a harvest-then-transmit protocol to improve the system energy efficiency (EE).
• Jointly optimized the active beamforming of the PS and the passive beamforming of the RIS.

Analysis of Signals and Communication Systems of NTU (Jan. 2021 - Feb.2021)

• Supervisor: Prof. Kah-Chan Teh (IEEE Senior Member), NTU
• Completed a task of the response of three paths wireless channels and the final report about "Analysis of Signals and Communication Systems" and won the Best Presenting Team.
