Built a long range RFID asset localization system based on TDoA and AoA techniques. Reduced cost and improved position accuracy over previous generation system.

• FPGA based SDR receiver with Xilinx Zynq SoC (Vivado)
• Algorithm development and simulation (Python NumPy, MATLAB)
• Product development and manufacturing
• 915 MHz RF front end design and prototyping
• Precision synchronization algorithms
• Solar energy harvesting
• FCC certification

Designed and implemented an SDR platform for near-field magnetic induction IP development, testing, and demonstration. Led the project and a team of 5 engineers from concept to release.

• Custom FPGA-based SDR transceiver with Altera Cyclone III (Quartus, DSP Builder)
• Ground-up design of PHY and MAC layers
• RFID and NFC protocols
• Hardware prototyping
