Abstract

The invention discloses a hybrid precoding method and system based on a reconfigurable holographic metasurface. The method includes: performing digital beamforming encoding on the target transmission signal according to the digital beamforming matrix; inputting the digital beam encoding signal into the feed source of the reconfigurable holographic metasurface antenna, and the reference wave carrying the target transmission signal sent by the feed source Entering the metamaterial radiation unit of the reconfigurable holographic metasurface antenna, the metamaterial radiation unit performs holographic beamforming encoding on the reference wave according to the holographic beamforming matrix, and sends the holographic beam encoding signal to the user. The invention can improve the communication quality while solving the problems of high antenna manufacturing cost and large power loss in the mobile communication process.

Description

[0001] This application claims the priority of the Chinese patent application filed with the China Patent Office on July 16, 2021, the application number is 202110807244.0, and the invention name is "A hybrid precoding method and system based on a reconfigurable holographic metasurface". The entire contents of this application are incorporated by reference. technical field [0002] The present invention relates to the field of wireless communication, in particular to a hybrid precoding method and system based on a reconfigurable holographic metasurface. Background technique [0003] To realize ubiquitous intelligent information networks, the upcoming sixth generation (6G) wireless communication places stringent requirements on antenna technology, such as capacity enhancement and precise beam steering. Although widely used dish antennas and phased array antennas are capable of achieving these goals, they both have their own inherent shortcomings that seriously hinder their fu...
