Fig. 7From: Two-way DF relaying assisted D2D communication: ergodic rate and power allocationErgodic rate performance comparison of the proposed power allocation strategy against different relay node locations and SNRs, including (d b1,d b2,d cr )=(5,5,5), β=0.5 for the left subfigure and (d b1,d b2,d cr )=(4,4,3), β=0.3 for the right one. The exact optimal results are presented for comparisonBack to article page
