Low density parity check (LDPC) code, which is a special case of error correction code with sparse parity-check matrix, has the performance very close to the Shannon Limit.
LDPC码是一种特殊的具有稀疏校验矩阵的纠错编码，其性能逼近香农限。
Fountain code is record-breaking sparse-graph code for channels with erasures.
喷泉码是一种在删除信道下性能优越的稀疏矩阵码。
However, the performance of LDPC code depends on the girth of its bipartite graph, that is it depends on its sparse parity-check matrices H, especially the complexity of encoding with H.
而LDPC码性能的优劣，与其二分图中是否存在短长度的圈有关，也即与其奇偶校验矩阵的构造有关。
