Measurement Matrix Data

[skywalker-xdu]

Hi Marius,

Thanks once again for your excellent work! Could you kindly share with me the measurement matrix data ‘measurementP_seed4321.mat’ in the ‘test_em_gm_amp.m’ file in MATLAB? Thank you.

Thanks for raising this, I will try to locate this file. In the meantime, please be aware that the matrices have all entries in the form

1/sqrt(2) * (+/- 1 +/- 1j)

Where both signs are chosen i.i.d. uniformly with probability 0.5.

Hi Marius，
Thanks for your reply. I also found some data missing, or maybe I didn't understand the meaning of file naming.

That path should either be the path to a trained final_model.pt file using train_score.py:

score-based-channels/train_score.py

Line 216 in a6ab760

os.path.join(config.log_path, 'final_model.pt'))

Or the path to a downloaded final_model.pt file downloaded from our Box folder.
