Abstract

The invention relates to a holographic beam forming method and system based on channel reciprocity and a storage medium. According to the method, after downlink channel information from a base station to each user is obtained according to channel reciprocity, a digital beam forming scheme and a holographic beam forming scheme based on the reconfigurable holographic metasurface are designed based on the downlink channel information and radiation amplitude of a metamaterial radiation unit in the reconfigurable holographic metasurface; a computer iterative algorithm is adopted to optimize a digital beam forming scheme and a holographic beam forming scheme based on a reconfigurable holographic metasurface, and then the optimized digital beam forming scheme and holographic beam forming scheme are adopted to perform communication control, so that the total data rate of a multi-user communication system can reach the maximum. Moreover, the method is mainly applied to communication between a base station comprising a reconfigurable holographic metasurface and a user, so that the blank of research on the holographic beam forming method of the RHS based on channel reciprocity in the prior art can be filled.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a holographic beamforming method, system and storage medium based on channel reciprocity. Background technique [0002] To realize ubiquitous intelligent information networks, the upcoming sixth generation (6G) wireless communication imposes stringent requirements on antenna technologies, such as capacity enhancement and precise beam steering. While the widely used dish antennas and phased array antennas are both capable of achieving these goals, they both suffer from their own inherent deficiencies that seriously hinder their future development. Specifically, dish antennas require heavy and expensive beam steering machinery, while phased arrays are highly dependent on power amplifiers, consume a lot of power, have complex phase shifting circuits, and have many phase shifters, especially in high frequency bands. Therefore, more cost-effective antenna techn...
