Work History
Project Lead-Low-Power Acoustic Modem
Harbin Engineering University
10.2024 - 05.2025
- Designed a QPSK-based modem on STM32H7; achieved 4.8 kbps at 12 kHz carrier with < 10-6 BER in pool trials.
- Implemented Sleep-Wake scheduler cutting idle draw to 8 mW, extending battery life by 38 % versus baseline.
R&D Intern
China Shipbuilding Industry Corp
06.2024 - 09.2024
- Assisted in prototyping a mid-frequency sonar projector: conducted impedance sweeps and beam-pattern measurements in anechoic pool.
- Analyzed deviations vs. theoretical directivity in MATLAB; findings adopted in the next design iteration.
Lead Author-IEEE OCEANS 2025 (Conference)
Harbin, China
11.2023 - 06.2024
- Paper title: “Self-Attention Multipath Noise Suppression for Shallow-Water Sonar.”
- Designed a lightweight Transformer that raised whale-click recall 79 % → 93 % on a 200 GB dataset; code released under MIT licence.
