Summary
👤
Senior🎓
Top SchoolTom Tsou is a Principal Engineer based in Boston with 14+ years building wireless systems from RF firmware to 5G machine learning. He has deep hands-on expertise in real-time SDR, MIMO-OFDM signal processing, and PHY/MAC development across projects from OpenBTS (GSM/GPRS) to commercial 4G/5G stacks at National Instruments and DeepSig. Tom combines low-level C/C++ and embedded firmware skill—optimizing SIMD on ARM/x86 and writing device drivers for Ettus USRPs—with higher-level ML-driven radio research for modern cellular networks. He is a frequent open-source contributor who has improved transceiver modules, added hardware support for USRP X300/X310, and implemented practical monitoring like clipping/overpower alerts that reveal an emphasis on operational robustness. His background blends academic EE training with production-grade test and interoperability work across standards bodies and Tier‑1 vendors.

3G UMTS Data Radio Access Network Node
Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:9 commits, 1 issue in 3 months
Contributions summary:Tom contributed significantly to the UHD (Universal Software Radio Peripheral) transceiver support, implementing device drivers and configurations for various Ettus Research devices. They added thread cancellation capabilities for clean shutdown and improved the receive signal processing, including scaling and pulse-shaping filter adjustments. They also fixed an issue in the UMTS uplink pilot scrambling and added receive overpower alerting.

GSM+GPRS Radio Access Network Node
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:8 commits in 7 months
Contributions summary:Tom primarily contributed to the `Transceiver52M` module within the `openbts` repository, focused on GSM+GPRS radio access network node functionality. Their work included fixing a register issue in complex-complex convolution, matching handover and slot mask flags with another transceiver module to enhance GPRS performance, and adding support for USRP X300/X310 hardware. The user also implemented clipping detection on RACH input to notify of overdriven gain levels.
