In this chapter, we study practical receiver designs for a point-to-point wireless link with SWIPT. We generalize the TS and PS schemes proposed in [9] to a general receiver operation scheme, namely, dynamic power splitting (DPS), by which the signal is dynamically split into two streams with arbitrary power ratio over time. Besides TS and PS, another special case of the DPS scheme, namely, on-off power splitting (OPS) is also investigated. Employing DPS, we propose an integrated receiver architecture, in which we integrate the ID and the EH circuits. In this architecture, the active RF band to baseband conversion in conventional ID is replaced by a passive rectifier operation, which is conventionally used only for EH. By providing a dual use of the rectifier, the energy cost for ID is reduced significantly. The RE performances for both conventional separated receiver in Fig. 1.4 and the proposed integrated receiver are further characterized. With receiver circuit power consumption taken into account, it is shown that the OPS scheme is optimal for both receivers. For the ideal case when the consumed power at the receiver is negligible, the PS scheme is optimal for both receivers. Finally, the performance for the two receivers are compared under a realistic system setup that employs practical modulation. The results show that for a self-sustainable system with zero-net-energy consumption, the integrated receiver achieves more rate than separated receiver at sufficiently short transmission distance.
