Simultaneous Wireless Information and Power Transfer (SWIPT) has attracted significant attention in the communication community. The problem of waveform design has however never been addressed so far. In this paper, we first investigate how a communication waveform (OFDM) and a power waveform (multisine) compare with each other in terms of harvested energy. We show that due to the non-linearity...

This paper considers simultaneous wireless information and power transfer (SWIPT) for a multiple-input multipleoutput (MIMO) relay system. The relay is powered by harvesting energy from the source via time switching (TS) and utilizes the harvested energy to forward the information signal. Our aim is to maximize the rate of the system subject to the power constraints at both the source and relay...

Temporal modulation of components electromagnetic systems provides an exceptional opportunity to engineer the response those in a desired fashion, both time and frequency domains. For engineering time-modulated systems, one needs thoroughly study basic concepts understand salient characteristics temporal modulation. In this paper, we carefully physical models bulk circuit elements---capacitors,...

Simultaneous wireless information and power transfer (SWIPT) is anticipated to have great applications in fifth-generation (5G) and beyond communication systems. In this paper, we address the energy efficiency (EE) optimization problem for SWIPT multiple-input multiple-output broadcast channel (MIMO-BC) with time-switching (TS) receiver design. Our aim is to maximize the EE of the system whilst...
