Codeword splitting protocol for SWIPT-based coded cooperation. The codeword c = (s1, s2, , sK, p1, p2, , pM) is split into two part, i.e., the sub-codeword \( \hat{\boldsymbol{c}}=\left({s}_1,{s}_2,\cdots, {s}_K,{p}_1,{p}_2,\cdots, {p}_m\right) \) with code rate r1and the remaining MEH = M − m check bits (pm + 1, pm + 2, , pM). The sub-codeword \( \hat{\boldsymbol{c}} \) is only needed for information decoding, and the remaining M − m check bits are used for energy harvesting
