Multi-user MIMO downlink transmission method adopting low-precision DAC under assistance of RIS

Номер: CN116545482A
Автор: LIANG XIAO, FANG WENHAO, ZHAO CHUNMING
Принадлежит:

The invention discloses a multi-user MIMO (Multiple Input Multiple Output) downlink transmission method adopting a low-precision DAC (Digital-to-Analog Converter) assisted by an RIS (Radio Information System). The method comprises the following steps: deploying downlink communication between a plurality of RIS assisted base stations and a multi-antenna user; one part of the transmitted signals which are pre-coded and quantized by the low-precision DAC directly reach a user, and the other part of the transmitted signals are reflected by the RIS and then reach the user; phase shifts of S groups of reflection coefficients are randomly configured for the RIS, and the base station calculates a precoding matrix by using a dimension reduction WMMSE algorithm according to downlink channel state information obtained by channel estimation or feedback; and traversing S groups of reflection coefficient phase shifts, recording the user weight and rate corresponding to each group of phase shifts, and ...
