Demo Lab Flow¶
This page summarizes the intended hands-on SDR workflow.
Objective¶
The goal is to connect theory, implementation and real measurements.
End-to-end engineering chain¶
reference model
-> FPGA waveform generation
-> RF transmission
-> independent reception
-> IQ recording
-> offline analysis
-> engineering report
Recommended hardware setup¶
| Device | Role |
|---|---|
| Zynq-7020 + AD9363 | signal generation and FPGA processing |
| RTL-SDR | independent external receiver |
| HDSDR | visualization and IQ capture |
| MATLAB / Python | offline analysis |
Suggested student experiment¶
Step 1 — Generate waveform¶
Create a clean reference waveform in software.
Step 2 — Run FPGA chain¶
Transmit the waveform using the SDR platform.
Step 3 — Observe spectrum¶
Verify:
- carrier frequency;
- bandwidth;
- spurious components;
- gain configuration.
Step 4 — Record IQ samples¶
Store IQ captures together with:
- sample rate;
- center frequency;
- gain settings;
- capture timestamp.
Step 5 — Analyze recording¶
Evaluate:
- FFT spectrum;
- constellation;
- synchronization quality;
- BER/EVM metrics.
Educational result¶
Students should see how a communication system behaves not only in simulation, but also in a real RF experiment.
