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 |
Vacant (\({V_{p}^{n}}\)) | \(\hat {V}_{p}^{n} \) | \(1 - P_{fa}^{n}\) | \(P_{l,1}^{n},P_{l,2}^{n}\) |
