Dual-Mode PSK Transceiver on SDR With FPGA

• GitHub: github.com/Teddy-van-Jerry/sdr-psk-fpga
• Report: go.wqzhao.org/sdr-psk-fpga

Note

This is a course project of Southeast University (2023 Fall).

Features

• BPSK/QPSK Modulation
• Coherent BPSK/QPSK Demodulation
• Carrier Synchronization (with Costas Loop)
• Symbol (Timing) Synchronization (with Gardner Loop)
• Packet-Based Communication
• Dynamic BPSK and QPSK Switching
• Pseudorandom (PN) Sequence Generator
• Block Diagram (with IP + Verilog RTL)
• Verified with Testbench
• Tested on SDR
• Pulse Shaping

You can explore details of implementations in the report.

Tip

The current design is resource-efficient. You have plenty of room to implement the remaining features to further enhance the platform.

Platforms

• SDR: eNodeX 30B
  • FPGA: Xilinx Zynq 7020 (xc7z020clg484-1)
  • 1Tx-1Rx with GSM Antenna (Max 2Tx-2Rx on SDR but we only use 1Tx-1Rx)
  • 4 GPIO as Output Signals (Max 8 GPIO Pins on SDR)
• Software
  • Vivado 2022.2 (To directly open the project, you need version >= 2022.2)
  • Matlab Filter Designer Toolbox (You can use alternatives to generate Xilinx .coe files)
  • LaTeX (My Version: TeX Live 2023 Latest)
  • Python >= 3.9 (For Data Processing in Report)
