Hardware meets software.软硬件协同设计。From FPGA fabric to real-time DSP.从 FPGA 逻辑到实时 DSP。
I'm an Electrical Engineering undergraduate at Northeastern University, focused on embedded systems, real-time audio, and FPGA-based robotics. I came to Northeastern through the NU-Immerse academic-English program. In my major coursework I've designed logic on FPGAs, built an autonomous walking robot, prototyped analog circuits, and written object-oriented C++; on internship I built a full-duplex acoustic echo canceller in Python for a robot intercom. Outside class, I teach math, physics, and engineering through LEGO robotics.我是东北大学电气工程专业的本科生，专注于嵌入式系统、实时音频与基于 FPGA 的机器人。我通过 NU-Immerse 学术英语项目进入东北大学。在专业课程中，我在 FPGA 上设计数字逻辑、搭建了一台自主步行机器人、制作并分析模拟电路，并编写面向对象的 C++；在实习中，我用 Python 为机器人对讲系统构建了一套全双工声学回声消除系统。课外，我还通过乐高机器人课程教授数学、物理与工程。

Hangzhou Boomy Intelligent Technology Co., Ltd.杭州景业智能科技股份有限公司
- Designed and implemented the robot-side full-duplex acoustic echo cancellation stack for a robot-to-operator intercom on a Rockchip RK3588S SoC: a multichannel frequency-domain Kalman adaptive filter with Hammerstein saturation-basis modeling of loudspeaker nonlinearity, decision-directed Wiener residual suppression, and minimum-statistics noise reduction — 3,700 lines of Python (numpy / scipy) across 16 modules.为机器人与操作员之间的对讲系统设计并实现了机器人端的全双工声学回声消除（AEC）软件栈，运行于瑞芯微 RK3588S SoC：多通道频域卡尔曼自适应滤波器、建模扩声器非线性的 Hammerstein 饱和基扩展、判决引导的维纳残余抑制，以及基于最小值统计的降噪 —— 共 3,700 行 Python（numpy / scipy），16 个模块。
- Built a 15-scene acoustic simulator and a gaming-resistant metric suite after establishing that the standard ERLE metric rewards half-duplex microphone gating; the delivered configuration averages 26.8 dB ERLE and 15.3 dB noise attenuation across the suite at 21 ms algorithmic latency and 9.9% of one core.在确认业界常用的 ERLE 指标会奖励“静音麦克风”的半双工行为后，构建了 15 个场景的声学仿真器与一套抗指标操纵的评测体系；交付配置在全部场景上平均达到 26.8 dB ERLE 与 15.3 dB 噪声衰减，算法延迟 21 ms，占单核 9.9%。
- Diagnosed loudspeaker distortion as saturation rather than polynomial after measuring 70,000× crest-factor amplification and 1e9+ condition numbers on speech, replacing the diverging polynomial basis with a bounded tanh basis and fixing a failure mode where nonlinear branches absorbed 95% of filter energy.实测语音下三次多项式基的峰值因数放大达 70,000 倍、相关矩阵条件数超过 1e9，据此判定扩声器失真的本质是饱和而非多项式，遂用有界的 tanh 饱和基替换发散的多项式基，解决了非线性分支吞掩 95% 滤波器能量的故障模式。
- Eliminated clock drift architecturally by running playback and capture in one duplex callback on a single sound card; brought up and calibrated the audio path across two SoC platforms (Raspberry Pi 4B, LubanCat-4) and traced a 6 dB performance ceiling to board supply noise, cutting the microphone noise floor by 16 dB.通过将播放与采集放入同一声卡的单个双工回调，从架构上消除了时钟漂移；在两个 SoC 平台（Raspberry Pi 4B、LubanCat-4）完成音频通路的硬件调试与标定，并将 6 dB 的性能天花板定位为板级供电噪声，使麦克风底噪降低 16 dB。
