Synthetic Radio Frequency Spectrum Snapshots Database for RFML

This database contains 391 {Y, W} pairs of images, where Y is radio spectrogram containing signals and W is noise distribution. Database was created with randomly selected:

• FFT sizes from set {1024, 2048, 4096, 8192}
• Time resolutions from set {256, 512, 1024, 2048} per second
• Sampling rates from set {2e6, 5e6, 10e6, 15e6, 20e6, 25e6, 30e6, 35e6, 40e6} in Hz
• Durations from set {0.25, 0.50, 0.75, 1.00} in seconds
• Waveforms from set {AM, FM, CW, LSB, USB, OFDM}
• PSNR from set {-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12} in dB

Note that spectrum was generated as REAL (not COMPLEX) - frequency axis resolution is fft_size/2.

Examples

On the left side is the radio spectrogram containing signals (Y), on the right side only noise distribution (W).
