Abstract

The problem of statistical computation of compression ratio for zero-order predictor with floating-aperture algorithm is considered. Markov Chain is proposed as the model of input process. By this

analytical expressions are derived for the mean and mean-square value of compression ratio

and then a simple and convenient algorithm is developed for the computation of these factors. Finally

several numerical results are given to demonstrate the effectiveness of this approach.
