Design principles for simultaneous wireless information and power transmission systems

By integrating conventional wireless power transfer (WPT) and wireless information transfer (WIT) into one efficient and creative transmission system, the simultaneous wireless information and power transfer (SWIPT) system has been considered as one promising paradigm for energy harvesting. To make the concept of SWIPT feasible and fully explore its underlying benefits, the practical system design is needed. In this paper, a potential SWIPT architecture with threshold-based switch (TBS) and signal mapping (SM) is proposed. The fundamental design principles, as well as several challenges are addressed based on the proposed architecture, which may provide the theoretical benchmark for the feasible system design in the future.
