| Abstract(in English) | It is well known that spatially-coupled (SC) codes with BP decoding have powerful error correction capability. However, the decoding performance of SC codes significantly degrades when they are used over burst erasure channels. In this paper, we propose two column permutations for parity check matrices: band splitting permutation and finer splitting permutation. The band splitting permutation splits a band in a base matrix into multiple bands. On the other hand, the finer splitting permutation resolves each band in a parity check matrix more finely into multiple bands. From computer experiments, it has been observed that the column-permuted SC codes based on the two proposed permutations show superior burst correction capabilities compared with those of the original SC-codes and other codes with comparable parameters. |
