From: Power control for cognitive relay networks with sensing uncertainties

Spectrum state CSS result Relative probability CR power
Occupied (\({O_{p}^{n}}\)) \(\hat {O}_{p}^{n}\) \(P_{d}^{n}\) 0,0
Occupied (\({O_{p}^{n}}\)) \(\hat {V}_{p}^{n}\) \(P_{md}^{n} = 1 - {P_{d}^{n}}\) \(P_{l,1}^{n},P_{l,2}^{n} \)
Vacant (\({V_{p}^{n}}\)) \(\hat {O}_{p}^{n}\) \(P_{fa}^{n}\) 0,0
