Abstract

See full text

The present invention discloses a near-field broadband uplink MIMO transmission method assisted by a dynamic metasurface antenna. The method includes: Broadband signals sent by a plurality of users distributed in a near-field region are processed with a large-size dynamic metasurface antenna as a receive antenna on a base station side, which can reduce system hardware costs and power consumption; and compared with the current hybrid beamforming based on a phase shifter and a conventional antenna, hybrid beamforming based on the dynamic metasurface antenna can effectively improve transmission performance. The present invention proposes an algorithm framework jointly designing a dynamic metasurface antenna and a baseband beamformer and including method such as matrix-weighted mean square error sum (MWMSE) minimization, alternate optimization, matrix vectorization, and MM. The present invention implements near-field broadband large-scale MIMO uplink transmission assisted by a dynamic metasurface antenna with low algorithm complexity and good convergence.
