Statement of the Problem: In order to satisfy the power-thirst of the IoT devices and thus extend their lifespan, the radio frequency (RF) signal aided wireless power transfer (WPT) is exploited for remotely charging. Carefully coordinating both the WPT and wireless information transfer (WIT) yields an emerging research trend in simultaneous wireless information and power transfer (SWIPT). However, the SWIPT system designed by assuming Gaussian distributed input signals may suffer from substantial performance degradation in practice, when the finite alphabetical input is considered. In this talk, we will provide a design guide of the coding controlled SWIPT and study the modulation design in both the single-user and multi-user SWIPT systems. We hope that this guide may push the SWIPT a step closer from theory to practice. Methodology & Theoretical Orientation: By controlling the output code word of a unary coding based encoder and by controlling the output symbols of a modulator, we are capable of shaping the corresponding waveforms sent in air by a SWIPT transmitter. A theoretical performance analysis and the optimal design have been conducted for improving the SWIPT performance. Findings: The impacts of both the coding and the modulation on SWIPT performance and the rationale behind have been firstly revealed. From the information theoretical perspective, the WIT and WPT are conflicted parties. Our design is capable of harmoniously coordinating both the WIT and WPT in the same spectrum. Conclusion & Significance: Due to the divergent characteristics of hardware, WIT and WPT have different requirements on RF signals emitted by SWIPT transmitters. Efficient coding and modulation approaches are designed for shaping RF signals so as to improve attainable SWIPT performance.
