Title:
LLR VALUE QUANTIFICATION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/236932
Kind Code:
A1
Abstract:
Disclosed in the present application are a log likelihood ratio (LLR) value quantification method and apparatus, an electronic device, and a storage medium. The method comprises: obtaining signal to interference plus noise ratio (SINR) linear values of a plurality of received symbols obtained by demodulation; calculating, on the basis of the SINR linear values of the plurality of received symbols, mutual information of the plurality of received symbols; and determining, according to an average value of the mutual information of the plurality of received symbols, a scaling factor for quantizing a plurality of LLR values, the plurality of LLR values comprising an LLR value of each received symbol obtained by performing calculation on the plurality of received symbols on the basis of an LLR algorithm.
