radio_dataset

Simulation of radio transmission within GNU Radio. The GRC flow graph is shown below.

python recipe/radio_dataset/file_transfer.py --wav-scp <wav.scp path> --replace-str <replace_string_for_new_audio path> --random-seed 1234 --rand-snr 1 --bandwidth nbfm

SNR is set to sampled from a Gamma disctribution whose mean is <rand-snr>.

Radio Audio Samples

The following audio samples are transimitted by the RACCT using HackRF One.
