Implementation of cyclostationary analysis:
requirements.txt - dependencies
analysis/src/audiosample.npy - sample array to verify computation
analysis/src/cyclostationary.py - estimates Spectral Correlation Density (SCD) using FFT accumulation (FAM) method
analysis/src/livescd.py - reads from microphone and plots scd using pyqtgraph
analysis/src/intro.ipynb - jupyter notebook showing SCD for different modulation types
analysis/gen/bpsk.py - generate bpsk file
analysis/gen/noise_bpsk.npy - generated by gen/bpsk.py
To verify:
python cyclostationary.py # should print "audiotest: PASS (error=0.0)" and show
To acquire audio from microphone and plot scf:
python livescd.py
