The problem of simultaneously optimizing the information rate and harvested power in a reconfigurable intelligent surface (RIS)-aided multiple-input single-output downlink multiuser wireless network with simultaneous transfer (SWIPT) is addressed. beamforming vectors, RIS reflection coefficients, split ratios are jointly optimized subject to maximum constraints, minimum realistic constraints on...

In the Industrial Internet of Things (IIoT), non-orthogonal multiple access (NOMA) has emerged as a viable method due to its superior efficiency. this paper, new power allocation technique for NOMA-enabled IIoT devices is presented with trade-offs between increasing energy efficiency and decreasing consumption. We present joint optimization transmission rate harvesting in simultaneous wireless ...

In this paper, we study information-theoretic limits for simultaneous wireless information and power transfer (SWIPT) systems employing a practical nonlinear radio frequency (RF) energy harvesting (EH) receiver. In particular, we consider a three-node system with one transmitter that broadcasts a common signal to separated information decoding (ID) and EH receivers. Owing to the nonlinearity of...

Communication between the primary and secondary sides is pivotal to wireless power transfer (WPT) system. The system control commands feedback information need simultaneous (SWIPT). In this paper, a FSK-based SWIPT with full-duplex communication via shared channel provided. Considering complexity of coupling relationship in kind system, paper proposes an analysis method based on transmission ch...
