Problems solved by technology

[0020] On the basis of the extended minimum sum decoding algorithm, the related technology further reduces the amount of calculation through the bubble check algorithm (Bubble check) and the simplified operation bubble detection algorithm; but compared with the extended minimum sum decoding algorithm, the bubble check algorithm and the simplified operation The bubble detection algorithm leads to a decrease in the performance of check node processing; therefore, a method that can not only reduce the calculation amount of check node processing, but also avoid the decline of check node processing performance, so as to further improve the performance of check node processing efficiency

Abstract

A method and device for realizing check node processing, including: sorting the information elements of each truncated information vector in ascending order according to the confidence value; determining the row and column of the log likelihood ratio according to a preset strategy; According to the log likelihood ratio, the sum of the confidence values ​​corresponding to each symbol value is obtained; the order of the symbol values ​​is determined according to the row and column of the log likelihood ratio, and the bit XOR operation of the symbol values ​​is performed based on the determined symbol value order; according to the log likelihood ratio The sum of the confidence degrees obtained by the comparison operation and the symbol value obtained by the bit XOR operation determine the processing result of the check node. In the embodiment of the present invention, while reducing the calculation amount of check node processing, it avoids the degradation of check node processing performance, and improves the efficiency of check node processing.

Description

technical field [0001] This article relates to but not limited to wireless communication technology, especially a method and device for implementing check node processing. Background technique [0002] Multi-ary low-density parity-check (LDPC) code decoding is applied to wireless communication systems, and the algorithm implementation is complex, including two parts: check node processing and variable node processing; among them, variable node processing is mainly based on channel information and check node The transmitted correction information calculates the confidence of the variable node (the confidence can be measured in the form of probability distribution or log likelihood ratio, both are equivalent); the verification node processing mainly calculates the correction information based on the confidence of the input variable node , the correction information is the confidence level of the sum of the input variables. At present, related technologies mainly study how to ...
