Abstract(in English) For the class of mixed channels decomposed into stationary memoryless channels, single-letter characterizations of the ε-capacity have not been known except for restricted classes of channels such as the regular decomposable channel introduced by Winkelbauer. This paper gives single-letter characterizations of ε-capacity for mixed channels decomposed into at most countably many memoryless channels with a finite input alphabet with/without cost constraints. For the case of finite input and output alphabets, a single-letter characterization of ε-capacity is also provided for mixed channels under a general mixing probability measure. It is shown that a given characterization reduces to the one for the channel capacity given by Ahlswede when ε is zero. In the proof of the coding theorem, the meta converse bound, originally given by Polyanskiy, Poor and Verdu, is particularized for the mixed channel decomposed into general component channels.
