摘要
本文以一阶平稳Gaussian Markov过程为信号源,分析直接法数据压缩技术的数据压缩比(DCR),对照模拟试验结果,理论公式和实验结果基本相符。
The direct methods of data compression are analyzed. Theoretical expressions are found for the data compression ratio between output and input sampling intervals of these devices when the input signal is a first-order Gaussian Markov process. The experimental results are in good agreement with the simulating tests.
