| Abstract(in English) | The universality of some variations of two-step lossless source codes using asymptotically sufficient statistics were proved by the authors. However, the theorem to show the weak universality could not be used to prove the strong universality. In this paper, a new theorem is established, and it is shown that the strong universality can be proved by combining the source approximation and the theorem which was used to show the weak universality in the previous result. Some two-step source codes including the MPM code and the two-step LZ78 code are proved to be strongly universal using the new theorem. |
