IQ Demo Dataset Manifest

This page documents the first small dataset contract for QPSK replay and future hardware captures.

Purpose

The repository should not store large raw IQ files directly. Instead, each dataset has a manifest that explains where the data comes from, how to verify it and which labs use it.

Demo dataset

Field	Value
Dataset	demo_qpsk_capture
Manifest	datasets/demo_qpsk_capture/manifest.yaml
Storage	synthetic or external
Intended use	QPSK constellation, EVM/SNR, replay checks
Required before hardware claim	checksum, capture settings, RF path, gain values

Required files

datasets/demo_qpsk_capture/
  README.md
  manifest.yaml

Optional files for future work:

preview_constellation.png
preview_spectrum.png
checksum.txt
download.txt

Acceptance criteria

A dataset is usable in the course when:

• sample rate is known;
• IQ format is known;
• center frequency or baseband reference is documented;
• checksum is available for real captures;
• access policy is clear;
• at least one analysis command is listed;
• expected metrics are defined.
