Figure 7From: Optimal blockwise subcarrier allocation policies in single-carrier FDMA uplink systemsFunction Γ(b) with N p = 64 , N u = 4 , L = 4 , and σ2(1) = 0.25,σ2(2) = 0.5,σ2(3) = 0.125,σ2(4) = 0.3 . For any b∗ ∈ β∗ = {1,2,4}, we have Γ( b ∗ )=(0.25+0.5+0.125+0.3) 64 4 2 =4.7.Back to article page
