BER performance of SWIPT-based QC-RA coded cooperation exploiting rate compatible characteristic. It is shown that the BER of the proposed system decreases sharply with the quality of S2-R channel becomes higher from supporting code rate r2 = 2/3 to supporting code rate r2 = 1. The more check bits exploited for EH by the rate compatible characteristic of QC-RA codes, the more energy harvested at the relay
