LDPC码及其基于概率测度的和积译码算法.在此基础上对算法作融合,引入对数似然比概念,阐述了基于对数似然比测度的和积译码算法,对其校验节点消息传递实现技-LDPC codes based on their probability measure and product algorithm. Based on this algorithm for integration, the introduction of the log-likelihood ratio concept, elaborated based on the likelihood ratio measure and product algorithm, the number of its school check node message passing techniques to achieve
