Abstract

The invention relates to a communication receiver system based on a reconfigurable holographic metasurface. The system comprises a reconfigurable holographic metasurface, a digital beam forming receiving module and a bias voltage control module. The reconfigurable holographic metasurface performs holographic receiving beam forming, converts the acquired spatial free electromagnetic waves into electromagnetic waves, and adjusts the collected energy of the electromagnetic waves to generate electromagnetic waves with different energies; the digital beam forming receiving module processes and separates transmitting signals of different users; and the bias voltage control module presets a bias voltage adjusting interval, so that the reconfigurable holographic metasurface adjusts the collection energy of the electromagnetic waves according to the preset bias voltage adjusting interval. Based on the structure, the total data rate of users can be maximized in multi-user communication. Moreover, the reconfigurable holographic metasurface assisted multi-user communication also has the characteristics of low power consumption and low hardware cost, and can solve the problems of large size, high power consumption, high hardware cost and the like of the existing antenna.

Description

technical field [0001] The invention relates to the field of wireless communication devices, in particular to a communication receiver system based on a reconfigurable holographic metasurface. 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 low power consumption hardware components. Among the existing antenna technologies, holographic antenna, as a small-sized, low-power planar antenna, has attracted more and more attention due to its low manufacturing cost and low hardware cost and multi-beam steering capability. Specifically, the holographic antenna uses metal patches to construct a holographic pattern on the surface, and records the interference between the reference wave and the target wave according to the interference principle. The radiation properties of the reference wave can then be...
