The wavelength is what determines light’s color, and these LEDs are amber (605-nanometer wavelength), light red (630 nm), deep red (680 nm), and near infrared (855 nm).

One of the key problems in spectrum sensing is to design the test statistic. Existing methods generally exploit the model-based features as the test statistic, such as energies and eigenvalues.
