Abstract

The invention relates to a beam forming optimization method and system of a holographic antenna based on discrete amplitude regulation and control. According to the beam forming optimization method of the holographic antenna based on discrete amplitude regulation and control, a digital beam forming scheme is obtained based on radiation amplitude and channel matrix design on the basis of a communication process between a base station comprising a reconfigurable holographic metasurface and a user; and after a holographic beam forming scheme is designed based on the transmission characteristics of the electromagnetic waves on the reconfigurable holographic metasurface, a final holographic beam forming scheme is determined in an iteration mode by adopting a joint optimization algorithm, and finally, a transmitted signal is processed according to the final holographic beam forming scheme, the total data rate of users is maximized while the blank that the influence of a holographic beam forming scheme based on discrete amplitude regulation and control for multi-user communication assisted by RHS on the performance of a communication system is not researched in the prior art is filled.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a beamforming optimization method and system of a holographic antenna based on discrete amplitude control. 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 ante...
