Abstract
(English)
Random number generation problem is one of the main topics in information theory. The resolvability problem is a kind of random number generation problems and formulated as follows. Given an arbitrary discrete random variables (called a source or a target random number), we generate it by using a discrete uniform random number whose size is as small as possible under the condition that the distance between the probability distribution of the source and the probability distribution of random variables to be generated is small.
One of main problems in this setting is to construct the efficient algorithm and the other is to show the achievable condition. The achievable condition for the source guarantees following. That is, there exists an algorithm under the condition that the distance between the probability distribution of the source and the probability distribution of random variables to be generated is small.
Steinberg et al.\ and Han et al.\ showed the achievable condition for an arbitrary given general sources by using information spectrum methods.
The class of general sources is quite large, so their result is very important. However their result is not so precise, since the general source has no assumption for the source such as the consistency condition.
On the other hand it is important to show the achievable condition more precisely by using the assumption for the source.
In this paper we show the achievable condition more precisely by using the asymptotic normality.
