In this letter, three hybrid simultaneous wireless information and power transfer (SWIPT)/ambient energy harvesting (EH) structures are analyzed for a relay node harvesting power from both a source node and the ambient environment. The EH structures are based on an ambient energy channel estimation power splitting scheme (ACEPS), an ambient energy data transmission power splitting scheme (ADTPS), and an ambient energy combination power splitting scheme (ACPS). Closed-form expressions of the achievable rates are derived. Numerical results are demonstrated to obtain the best proportion from these different schemes.
