Error Exponent of Coding for Stationary Memoryless Sources with a Fidelity Criterion
Shunsuke Ihara · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2005
We investigate the error exponent in the lossy source coding with a fidelity criterion. Marton (1974) established a formula of the reliability function for the stationary memoryless source with finite alphabet. In this paper, we consider a stationary memoryless source assuming that the alphabet space is a metric space and not necessarily finite nor discrete. Our aim is to prove that Marton's formula for the reliability function remains true even if the alphabet is general.
