Title:
METHOD AND APPARATUS FOR DESIGNING HYBRID PRECODER OF LARGE-SCALE MIMO TRANSMITTER
Document Type and Number:
WIPO Patent Application WO/2022/227899
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for designing a hybrid precoder of a large-scale MIMO transmitter having low complexity. The method comprises: according to known channel matrix information, using a greedy algorithm and phase matching to design an analog precoder; and according to equivalent channel information composed of a channel matrix and the analog precoder, using a water injection algorithm to design a digital precoder. The method can achieve with low complexity the design of a hybrid precoder having a dynamic sub-connection structure, and can achieve a high spectral efficiency and energy efficiency.
