本文研究浮窗零阶预测算法所获压缩比的统计计算问题。首先依据马氏链模型推导压缩比的均值和均方值的解析表达式
继而提出一种计算它们的简便算法。最后给出若干数值计算结果。
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.
