Abstract
(English)
The universal lossless source coding problem is one of the most important problem in communication systems. The aim of source coding is to compress data to reduce costs in
digital communication. Traditional universal source coding schemes are usually designed for stationary sources.
Recently, some universal codes for nonstationary sources have been proposed. Independent piecewise identically distributed (i.p.i.d.) sources are simple nonstationary
sources that parameter changes discontinuously. In this paper, we assume new i.p.i.d. sources class, and we prove that Bayes codes minimize the mean redundancy when parameter
transition pattern is known and parameter is unknown.
