Abstract
Spatially-coupled (SC) codes are constructed by coupling many regular low-density parity-check codes in a chain. The decoding chain of SC codes aborts when facing burst erasures. This problem cannot be overcome by increasing the chain length. In this paper, we introduce multi-dimensional (MD) SC codes to circumvent it. Numerical results show that two-dimensional SC codes are more robust against the burst erasures than one-dimensional SC codes. Furthermore, we consider designing multidimensional SC codes with smaller rateloss.
