摘要
Abstract
In future 6G Internet of Things(IoT)systems,extensive deployment of pivotal technologies such as high-frequency mil-limeter waves and terahertz spectrum makes it possible for wireless transmission among network devices situated in the near-field re-gion.As a byproduct,Dynamic Metasurface Antenna(DMA)and other small-sized antenna arrays have been widely applied in this scenario due to their advantages in transmission efficiency,physical size,and power consumption.And related research has received increasing attention.Aiming to improve the energy performance of receivers in near-field wireless transmission,a downlink near-field wireless Simultaneous Wireless Information and Power Transfer(SWIPT)system based on DMA is proposed.Under the condition of satisfying the minimum transmission rate requirements of all information users,an efficient solution for jointly optimizing the tunable frequency response matrix of DMA and the digital precoding vector is proposed for this optimization problem.In addition,the influences of factors such as the distance between users and the minimum Signal to Interference plus Noise Ratio(SINR)on the system perform-ance are also discussed on this basis.Simulation results show that the scheme proposed in this paper can effectively improve the joint performance of wireless information and power transmission compared with other existing technologies.关键词
