摘要

许多系统的输出是一维离散信号，本文一般性地研究了该类信号的特点，给出了一种有效的压缩表示方法，在压缩比为１０～２０倍时，恢复信号的信嗓比仍然是较高的．

Abstract

In the realm of DSP（Digital Signal Processing）

much attention is focused on finding a good way to compress digital signals.Here we study the general features of 1-D digital signals and explore an efficient hybrid description method based on statistics and PIFS. While the compression ratio is between 10 and 20

the SNR of recovered signals is still quite high.
