Tiivistelmä

This contribution evaluates and optimizes the performance of simultaneous wireless information and power transfer (SWIPT) with an integrated energy and information receiver, which is characterized by low complexity and energy cost. To this end, a tractable expression for the achievable rate is derived, which is subsequently used to quantify the achievable harvested energy-rate region for the considered time-switching (TS) protocol. Sequential reception of energy and information can be implemented with the aid of TS, which also reduces complexity whilst it is useful in applications that the receiver does not have to be continuously active. In this context, the joint harvested energy-rate outage probability is also defined and minimized for a point-to-point and multicasting system, determining the optimal TS factor. Finally, respective computer simulations corroborate the effectiveness of the proposed framework, whilst interesting insights are developed which are expected to be useful in the design and effective operation of TS wireless power systems.
