我们构造了一类新的低密度奇偶校验(LDPC)码集,它们是传统的非规则LDPC码集的子集,并发展了这些码集的密度演化。此外,我们还发现了一个比它的超级系综具有更好阈值的系综。
We construct new families of low-density parity-check (LDPC) code ensembles which are subensembles of conventional irregular LDPC code ensembles and develop density evolution for those ensembles. Further, we find an ensemble which has a better threshold than that of its super ensemble.
