Average bandwidth of the detected spectral hole with target P FA  = 0.1. Using sample complexity of 250 samples under frequency-selective channel model for (a) ideal model, (b) Rapp PA with 15 dB back-off as the modest case, (c) Rapp PA with 5 dB back-off as the worst case. Different combinations of FFT/AFB-based sensing and OFDM/FBMC based PU waveforms.
