Figure 13From: Optimal blockwise subcarrier allocation policies in single-carrier FDMA uplink systemsThe correlation function ΓCFO(b,δf) as function of b for the scenario: N p = 64 , N u = 2 , L h = 8 , and σ h ( 1 ) 2 = 0.25 , σ h ( 2 ) 2 = 0.5 , δf∈{0.1,0.2,0.3,0.4} . The optimal block-size minimizing the correlation function is b max ∗ = N p LN u =4.Back to article page
