From: Multisource SWIPT-based coded cooperation:rate compatible codes and codeword splitting protocol
Comparison of the proposed codeword splitting protocol and other SWIPT protocols. It can be seen that the power splitting protocol and the time switching protocol are both carried out during each bit period. However, the proposed codeword splitting protocol is only operated one time during the whole codeword period. Hence, the codeword splitting protocol is with the characteristics of lower complexity, higher efficiency, no strictly bit synchronization limitation, and less hardware requirement
