Figure 12From: Multi-antenna spectrum sensing by exploiting spatio-temporal correlation AUC curves (solid lines for channel delay spread 0 . 779 μ s and dashed lines for channel delay spread 0 . 097 μ s) to assess the effects of number of samples M : number of vector samples per sub-block N = 15, number of antennas L = 4, and average SNR κ ̄ =-8dB .
