| Abstract(in English) | The second-order achievable rate region in Slepian-Wolf source coding problem is determined. The second-order achievable rate, which enables us a finer evaluation of the achievable rate, has been introduced and analyzed for general sources in the single source coding problem. Analogously, in this paper, we first define the second-order achievable rate region for the Slepian-Wolf coding problem and establish the source coding theorem in the second-order sense. The Slepian-Wolf coding problem for the correlated source is one of the typical problems in the multi-terminal information theory. Miyake and Kanaya, and Han have established the first-order source coding theorems for general correlated sources. On the other hand, there are few researches on the second-order achievable rates for the Slepian-Wolf coding problem. Our analysis concerning the second-order achievable rates for general sources is on the basis of the information-spectrum methods. Moreover, we compute the explicit second-order achievable rate region for i.i.d. correlated sources using the relevant asymptotic normality. |
