Did you know?
WebAn end-to-end joint source–channel (JSC) encoding matrix and a JSC decoding scheme using the proposed bit flipping check (BFC) algorithm and controversial variable node selection-based adaptive belief propagation (CVNS-ABP) decoding algorithm are presented to improve the efficiency and reliability of the joint source–channel coding (JSCC) … Web2 days ago · Backward decompositions, such as Layer-wise Relevance Propagation (LRP; Bach et al., 2015), on the other hand, attribute relevance to input features by decomposing the decoding decision of a DL model in a backward pass through the model into the contributions of lower-level model units to the decision, up to the input space, where a …
WebBased on the LLR-BP decoding algorithm, an improved belief propagation (IBP) decoding algorithm which uses soft information by last decoding is proposed. When the CRC is failed, the soft information from the last decoding, which is higher than the threshold, is reserved as the initial information of the following decoding, which greatly improves the decoding … WebWhat is claimed is: 1. A decoding apparatus comprising: an input unit configured to receive encoded data as input data; a check node processing unit configured to update an extrinsic value ratio based on a prior value ratio for each row of a parity check matrix with respect to the data input via the input unit; an input unit configured to receive
