基于可重构智能表面的信息调制与空分多址
Information Modulation and Space Division Multiple Access Based on Reconfigurable Intelligent Surface
摘要
Abstract
To solve the problem of high radio frequency cost and power consumption in current large-scale antenna systems,the research on reconfigurable intelligent surface(RIS)technology is intro-duced in new transmitter designing.An RIS-based information modulation and space division multi-ple access scheme is proposed,which has low hardware complexity,low cost,power efficiency and easy integration.Information is modulated by controlling RIS reflection coefficients,and multi-beam containing different information for multi-users,is formed simultaneously,which realizes space divi-sion multiple access for multi-user.Taking dual-stream transmission for dual-user as an example,the implementation of the scheme is given based on binary particle swarm optimization algorithm,and relevant simulation evaluation is carried out.The simulation results show that the proposed scheme can complete the 2 amplitude shift keying(ASK)modulation of dual-current signal at the same fre-quency for dual users,and send it to the users through space division multiple access.关键词
