无线数据与能量协同传输技术:编码与调制设计

Simultaneous Wireless Information and Power Transfer: Coding and Modulation Design

利用射频(RF)信号的远场传输特性,无线数据与能量协同传输技术(简称为无线数能同传)(SWIPT)可以将数据与能量通过同一无线射频信号传输到通信设备,从而同时满足设备的通信与用能需求。该技术的实现需要从硬件方面对无线射频电路、收发天线以及电磁波束重新设计以提升无线能量传输(WPT)的效率,另一方面也需要在信息和通信理论方面取得突破,实现编码和调制级别的SWIPT控制。

Thanks to the far-field transmission characteristics, radio frequency （RF）signals can be relied upon for realising simultaneous wireless information and powertransfer （SWIPT）. Thus, both the communication and charging requests of devices aresatisfied. In order to make SWIPT a reality, wireless RF circuits have to beredesigned for improving the efficiency of wireless power transfer （WPT）. Thebreakthrough in the classic information and communication theory has to be achievedin order to control SWIPT in both coding and modulation levels.
