The sum-product algorithm, which belongs to the class of message-passing algorithms, is an iterative decoding algorithm for LDPC codes that is based on passing likelihood ratios between variable and check nodes. The variable nodes receive the outputs of the channel and pass the likelihoods of cod...

Through extensive numerical experiments, we show that the sum-product algorithm returns very accurate blocking probabilities and greatly outperforms the reduced load approximation for loss networks with a variety of topologies. The factor graph model also provides a promising approach for analyzing product...

We use this method with high dimensional parity codes and array-LDPC codes as its constituent codes. We show that we can employ the sum-product algorithm with appropriate likelihood functions in this scheme and analyze the performance of these coding schemes.关键词:...

Sum-Product算法如下: Sum-Product(x){ if(x是变量节点){ if(x为叶子节点) return 1; subFx = {x的子节点(全为因子节点)}; result = 1; for(x_i in subFx){ result = result * Sum-Product(x_i); } return result ; } if(x是因子节点) { if(x是叶子节点) return f(xp);//f为x表示...
A simple, yet effective decoding algorithm is proposed for low-density parity-check (LDPC) codes, which significantly simplifies the check node update computation of the optimal sum-product algorithm. It achieves essentially optimal performance by applying scaling in the decoder's extrinsic information....
