My current research interests lie in the fields of green communication, channel modeling, wireless ray tracing, adversarial communication, satellite 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)
• Developed a novel metric, Waste Factor, to evaluate power efficiency in ANY cascaded systems.
$$W = W_N + \frac{(W_{N-1} - 1)}{G_N} + \frac{(W_{N-2} - 1)}{G_N G_{N-1}} + \cdots + \frac{(W_1 - 1)}{\prod_{i=2}^N G_i}$$
• Enhanced Waste Factor for data center analysis using power usage effectiveness (PUE).
• Simulated component efficiency impacts on Waste Factor at different frequencies in a 1 km² cellular cell.
• Extended the metric to analyze parallel/MIMO systems and radio access networks (RAN), and help drive decision making for wireless networks.

• Supervisor: Prof. Theodore S. Rappaport (Member of US National Academy of Engineering, Founding Director of NYU WIRELESS, IEEE Fellow)
• Conducted comprehensive FR3 measurement campaigns at NYU for 6.75 GHz and 16.95 GHz frequencies.

• Supervisor: Prof. Sundeep Rangan (Director of NYU WIRELESS, IEEE Fellow)
• Derived the worst-case adversarial capacity for binary channels with a time-bounded adversary.
• Developed a method using random interleaver and thresholded LLR decoder to achieve optimal capacity.
• Demonstrated successful integration of the proposed method into 5GNR LDPC decoder architectures.

Material-Aware 3D Scene Reconstruction for Wireless Ray Tracing (Sept. 2024 - Now)

• Supervisor: Prof. Theodore S. Rappaport and Prof. David Fouhey
• Pioneered an AI-powered automated framework for material-embedded 3D modeling, revolutionizing wireless ray tracing simulation accuracy for mmWave and sub-THz frequencies.
• Developed an innovative multi-stage pipeline combining transformer-based semantic segmentation (SAM2/VLLM) with high-resolution 3D reconstruction (MASt3R-SfM) to map material properties seamlessly.
• Validated framework effectiveness using NVIDIA Sionna RT, demonstrating significant improvements in channel impulse response prediction and multipath propagation modeling for indoor environments.

Resource Allocation for Wireless-Powered Backscatter Networks (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.
