The sum rate as a function of the interlink distance dL in a two-link system. Figure 3 provides the results of sum rate versus the interlink distance dL. Each link represents the sum rate under the different interlink distance. And the different types lines represent the proposed IWFA scheme and the unaided scheme under different conditions of P max ∈{20dB,30dB} and σ2∈{0.5,1.0}
