Problems solved by technology

[0004] As the number of iterations is updated, the C2V information becomes more and more accurate, while the channel information may still retain the original error information, which will reduce the rate at which the verification converges to the correct codeword, resulting in a slow decoding response rate.

Abstract

The invention discloses an information processing method, a storage device and an electronic device. The information processing method comprises steps of determining a first weight and a second weight for performing mth variable node updating, wherein the first weight is the weight of channel information used by the variable node for updating, the second weight is the weight of the first information used by the variable node for updating, and using the first weight and the second weight to perform mth variable node updating to obtain the updated information of the mth variable node. The first information is the information transmitted by a verification node to a variable node and the m is a positive integer.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to an information processing method, a storage device and an electronic device. Background technique [0002] Low Density Parity Check code (Low Density Parity Check, LDPC) decoding algorithm is that the confidence information is iteratively updated between the check node (Check Node, CN) and the variable node (Variable Node, VN), while using the posterior The log-likelihood ratio (LLR) of the probability is used as a measure of confidence. [0003] In the iterative update phase, the variable node receives the (Check node to Variable node, C2V) information transmitted by the connected check node to the variable node; at the same time, the variable node also receives the confidence of the symbol symbol from the channel information. The channel information and C2V information are calculated at the variable node to obtain variable node to check node (Variable node to che...
