From: Multisource SWIPT-based coded cooperation:rate compatible codes and codeword splitting protocol
BER comparison of SWIPT-based QC-RA coded cooperation with codeword splitting protocol and power splitting protocol. When the energy utilization ratios are the same, it is shown that the BER performance of the codeword splitting protocol is almost the same with the power splitting protocol. However, the energy utilization ratio of the power splitting protocol actually decreases, and the time delay at the relay is longer and the complexity is higher
