Abstract
A method for selecting a pre-coding matrix, and a device and a telecommunication system for implementing the method are provided. The method includes calculating an effective signal noise ratio (SNR) at each layer for each pre-coding matrix, comparing the lowest SNR at each layer for each pre-coding matrix against the threshold SNR, selecting a proper pre-coding matrix, and considering high and low SNRs of a system during selection of a pre-coding matrix to achieve good pre-coding effects and improve the system performance.
