アブストラクト
In this paper, we deal with the fixed-length lossy compression with the ε-fidelity criterion which is a kind of the distortion criterion such that the probability of exceeding a given distortion level is less than a given probability level. Then, we give an achievability bound and a converse bound of the minimum number of codewords with this criterion, where we introduce a new covering lemma to prove the achievability bound. We show that our converse bound is tighter than that of Kostina and Verdu. Furthermore, we show a numerical example which demonstrates that our achievability bound is tighter than that of Kostina and Verdu for short blocklengths.
