| Abstract(in English) | We develope two methodology of constructing irregular low-density parity-check (LDPC) code for correcting a burst erasure. With high probability, the performance degradation is caused by producing small size of stopping sets of many degree two variable nodes. In this paper we present effective variable node reordering method to increase minimum span of stopping sets (MSSS) by using the special structure of degree two variable nodes of extended irregular repeat accumulate (eIRA) codes. The proposed two codes have also efficient encodable property since they are the class of eIRA codes. Furthermore we present construction method of irregular LR-LDPC which are known to have large MSSS. From the experimental results, we show that MSSS of the proposed codes are larger than the conventional ones. |
