GUANXUN LIN

1. Using Xilinx and Quartus in the repeater system core" FPGA and ADI RFIC " to detect LTE/NR IQ signal and perform corresponding signal processing( DDC / DUC / Single rate Filter Designed / Signal Clipping / AGC / ALC / DPD / OFDM ( FFT / IFFT) )
2.Familiar with repeaters in 3GPP specifications and design related performance
3. Use kintex 7 (7k70T/7k160T) or Zynq UltraScale+ MPSoC to verify the peripheral hardware circuit design, and also need to understand the hardware circuit design (UART/PHY/EEPROM/Fiber Optic/DDR4/DDR5 / RF(Mixer/ LNA/HPA) )
4. Optimizing FPGA design to ensure the best balance of performance and resource utilization thus involves timing/area analysis and constraints, the possibility of performance optimization on DSP to meet end customer requirements
5. Understand the operation and interface (DDR / JESD204B) of ADI RFIC (AD9361 / AD9371 /ADRV9009) and implementation in FPGA
6. Understand Adaptive filter theory and implenment in FPGA to let Repeater more convenient to use in the field.
