Description

technical field [0001] The invention belongs to the technical field of wireless data and energy simultaneous interpretation, and in particular relates to a joint modulation and coding algorithm for wireless data and energy simultaneous interpretation. Background technique [0002] In the past decade, wireless power transfer (WPT) has attracted widespread interest in the field of wireless communications. By equipping the receiver with energy harvesting circuitry, low-power devices are made ready to harvest wireless power when they are hungry, and extend their useful life. Coordinated Wireless Information Transfer (WIT) and WPT lead to the birth of Wireless Simultaneous Interpretation (SWIPT) technology. Some conventional studies have proposed methods to coordinate WPT and WIT, such as enabling wireless information and power to be transmitted in different time slots by using time switching (TS), or by equipping power distribution circuits to divide the received power into Th...
