Fig. 4From: Power allocation for SWIPT in K-user interference channels using game theoryThe average transmit power as a function of the harvest energy threshold. Figure 4 shows the results of the average transmit power versus the harvest energy threshold. The different types of lines represent the proposed IWFA scheme and the unaided scheme under different conditions of K∈{3,4} and α ∈{0.5,0.6,0.7}Back to article page
