MultipleSignalClassification

Subspace-based (MUSIC / ESPRIT / Matrix Pencil) time-delay estimation for IEEE 802.11n WiFi L-LTF signals. Research paper to be published.

Layout

  • src/musicssvd/ — the installable package
    • generator.py — DataGenerator: L-LTF signal/channel generation and transmission
    • processor.py — DataProcessor: TDE algorithms (cross-correlation, MUSIC, ESPRIT, matrix pencil)
    • evaluator.py — Evaluator: accuracy metrics against ground truth
    • plotter.py — Plotter: result visualization
    • music.py — MUSICTDE: high-level facade wiring the above together
  • scripts/run_tde.py — demo entry point, runs and plots all TDE methods
  • examples/basic_usage.py — minimal, clean example of the core API (start here)
  • examples/forward.py, examples/forward_scan.py, examples/time_varying.py — exploratory research scripts (template-length scans, time-varying/Doppler channel demo); heavier on ad-hoc plotting, not meant as API references

Install

pip install -e .

Run

python examples/basic_usage.py
python scripts/run_tde.py
