This paper considers simultaneous wireless information and power transfer\n(SWIPT) over a dual-hop dynamic decode-and-forward (DF) relay network with the\npower-splitting (PS) energy harvesting protocol at the relay. The circuit power\nconsumption (CPC), which includes power requirements for both decoding and\nencoding circuits, is considered at the relay. For a rate-dependent linear CPC\nmodel, we formulate an optimization problem to decide the optimal throughput,\nPS ratio, relay transmit power and time ratio for the source to relay\ntransmission. Although the resultant optimization problem is non-convex, we\nderive an efficient optimization algorithm, requiring significantly less\nfloating point operations than an interior point method. Finally, we present\nnumerical results which lead to some interesting insights for system design.\n
