| Abstract(in English) | The MPM code can attain O(1/log n) maximal redundancy, but its coding is off-line. On the other hand, Takekawa-Yamamoto proposed a sequential MPM coding algorithm, and showed that it can attain the maximal redundancy O(1/log n). Moreover, they also proposed a modified sequential MPM coding algorithm to improve the compression rate of practical files. However, the modified coding algorithm is not quaranteed to attain the maximal redundancy O(1/ log n). In this paper, a new improved sequential MPM coding algorithm is proposed. Furthermore, it is proved theoretically that the proposed coding algorithm can attain the maximal redundancy O(1 / log n), and it is showed that it is more efficient than the original MPM code and sequential MPM code by compressing a corpus. |
