Figure 5From: Energy-efficient cooperative spectrum sensing schemes for cognitive radio networksROC curves comparison of the detectors when SNR is equal to −10 dB. In the first TSEEOB-CSS algorithm, λ1 is 1.10 when P f ∈ (0, 0.05], λ1 is 1.05 when P f ∈ (0.05, 0.1], and λ1 is 1.00 when P f ∈ (0.1, 0.2].Back to article page
