ABSTRACT:
More code words are assigned to the data word. There are 71949 code words that can take the start point at the state4and there are 71949 code words that can take the start point at the state5, and out of these code words, there are 27126 duplicate code words that can take the start point at both the state4and the state5. In this example, the duplicate code word can be discriminated during decoding, and therefore assigned to the data word in one-to-one relation. Because 44823 (=71949−27126) code words that can take the start point at only the state4and 44823 code words that can take the start point at only the state5are different from each other, two code words, namely a code word that can take only the state4and a corresponding code word that can take only the state5are assigned to one data word. In other words, 71949 (=44823×2÷2+27126) code words are selected.
