| Abstract(in English) | In this paper, we construct two-dimensional constraint codes basedon fixed-length column by column coding and derive a lower bound of its achievable rate. In general, it is a difficult problem to calculate the channel capacity of a two-dimensional constraint code, and exact values ??of channel capacity are known only for limited two-dimensional constraints. In this work, we consider coding problems of two-dimensional constraint codes based on fixed length column by columnsequence coding. The goal of this research is to derive a lower bound of the achievable rateunder the assumption where fixed-length column by column encoding is used. The lower bound is evaluated based on the density of a state transition graph composed of the allowable sequences pairs as vertices. |
