Figure 9From: Joint optimization of detection threshold and resource allocation in infrastructure-based multi-band cognitive radio networksThe unique solution of OPA The OPA is the unique point of intersection between the curves of f 2 ( p k , n ∗ ) = p k , n ∗ + 1 α k , n and f 2 ( p k , n ∗ ) = 1 − P n fa ( λ n ) + P n md ( λ n ) ( μ + β n ) ln 2 − f 1 ( p k , n ∗ ) .Back to article page
